Introduction

Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices

Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.

The three types of advisories are defined as follows:

**** Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

**** Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.

Indicates a situation that could result in equipment or property-damage only accidents.

Important Environmental Concerns

Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.

Important Responsible Refrigerant Practices

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.

Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:

• Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
•  When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labeling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.

• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS) policies when performing work such as hot work, electrical, fall protection, lockout/tagout, refrigerant handling, etc. Where local regulations are more stringent than these policies, those regulations supersede these policies.
• Non-Trane personnel should always follow local regulations.

General Information

Overview

Proper Operation!
Failure to take these precautions could result in death or serious injury or possible equipment or property only damage.
Any persons installing, operating, maintaining, or working in the vicinity of a heat exchanger must be properly instructed to do so safely. The user is responsible for taking precautions including, but not limited to:

• Adhering to national and local safety regulations
• Ensuring the heat exchanger is only operated in perfect condition
• Performing required maintenance
• Only operating the heat exchanger at temperatures, pressures, and with flow medias that are within the allowable limits of the heat exchanger

This IOM instructs on the proper handling, installation, and maintenance of Trane Rental Services temporary heat exchangers. The temporary heat exchangers are plate and frame type and provide fluid-to-fluid heat exchange in chilled/hot water applications. The primary function of a heat exchanger is to allow heat transfer from one water loop to another without letting the two water loops come in direct contact.

Identification

Each heat exchanger is provided with a stamped nameplate which includes:

• Serial No.
• Model No.
• Permissible Pressures
• Permissible Temperatures
• Test Pressure
• Compression Dimensions

Heat Exchanger Plates

• Chevron pattern plates
• For use with relatively clean media (low viscosity and high operating pressures)
• Stainless Steel 316

Gaskets

High Operating Pressures!
Operation with inadmissible temperatures, pressures, or flow media can cause gasket failure. Gasket failure could cause internal leaks that would mix fluids, and could result in sudden release of contents under high pressure, which could result in death or serious injury or possible equipment or property-only damage.
The gaskets are used to contain the flow medias inside the heat exchanger and isolate the two flow medias from each other. The sections that isolate the two medias are double gaskets which create a leakage cavity. If there is an internal leak, the leak can escape outside of the heat exchanger via grooves in the intermediate gasket. The internal leaks can easily be identified. Gaskets are NBR (Nitrile) material. Their attachment to the plates is glueless.

Through a series of contoured plates and gaskets, the two fluid loops are provided with a large amount of surface area to perform an exchange of heat, but are kept completely separate to avoid mixing of the two loops.

Application Considerations

Temporary heat exchangers have many uses that can complement a rental chiller or cooling tower, or be used to temporarily take the place of a non- functioning heat exchanger:

Temperatures Out of Range

If a process requires cooling, but the temperatures are too high to allow the use of a standard chiller, a heat exchanger may be used. The chiller, for example, can operate at its standard temperatures while the customer’s process (perhaps a bath which is used too cool parts that have just been machined) can operate at the high temperatures needed to ensure proper operation.

Flow Out of Range

If a process requires cooling, but the flow rate is too low or too high for a standard chiller of corresponding tonnage, then the use of a heat exchanger can allow the chiller to operate at a flow rate that meets specification while the customer’s process can operate at its optimal flow rate.

Cooling Tower Conversion

A heat exchanger can be used in combination with an open loop cooling tower to perform the same function as a closed loop cooling tower. Sometimes the use of certain chemicals eliminates the possibility of using an open loop cooling tower. Additionally, sometimes a system must be protected from pollution of the water that can result from using an open loop cooling tower, such as a water source heat pump system.

Incompatible Fluids

If a process requires the cooling of a fluid not suitable for use in a standard chiller, contact Rental Services. A heat exchanger can be used in combination with a rental chiller to provide cooling to the fluid without requiring it to actually pass through the evaporator.

Selection Procedure

Temperatures

Fluid temperatures permitted in the heat exchanger are limited by the gasket material. Rental Services heat exchangers are fitted with Nitrile (NBR) gaskets with operating temperature limits of 14°F to 250°F (-10°C to 121°C).

Fluid

Fluids allowed through temporary heat exchangers are determined on a case by case basis. In all cases, compatibility is checked against the gasket material (Nitrile or NBR) and the plate material (Stainless Steel 316).

Pressure and Pressure Drop

For applications up to 150 psi, Rental Services temporary heat exchangers may be used in combination with our flexible rental hose. Temporary heat exchangers being used without flexible rental hose are rated for a maximum operating pressure of 300 psi.
The pressure drop due to friction loss through the heat exchanger is dependent on the fluid type and the flow rate and can be provided upon request.

Flow

There is a wide range of flows allowed. See the specifications for each product for approximate minimum and maximum flows. Minimum and maximum flows are also dependent on fluid type and can be provided upon request.

Installation and Decommission

Please read the entire contents of this section before attempting off-loading or installation.

Off-Loading

Heavy Objects!

Failure to properly lift unit could result in death or serious injury or possible equipment or property-only damage. Any forklift, crane, and straps or chains used must be capable of supporting the weight of the unit.
Inspect the unit before unloading and/or installing. If there is any damage, contact Trane Rental Services.
If using a crane, ensure the crane and any straps or chains being used are able to support the weight of the unit. When attaching any straps or chains used for lifting, connect them only to the four lifting lugs provided at each corner of the unit. Do not use the lifting lugs mounted on the heat exchanger itself. These lugs are only to be used if it is required to remove the heat exchanger from the base. Consult Trane Rental Services before attempting to remove the heat exchanger from the surrounding base and frame.
If using a forklift, first ensure the forklift is able to safely support the weight of the unit. Only use the provided fork pockets.
During the lift and the movement of the unit, all personnel should wear appropriate Personal Protective Equipment (PPE) including, but not limited to, hard hats, steel toed shoes, and safety gloves. People should not stand close to, or under, a unit that is being lifted or moved. A chain/strap or hoist failure should always be considered a possibility, and as such, all personnel should stand clear.

Placement

Locate the heat exchanger on a flat, level, clean surface that is capable of supporting the unit’s weight. Consider the following when choosing a location for the unit:

• Minimizes the length of piping required
• Isolated from sources of electricity
• Would not be affected by a water leak
• Accessible in the event of an emergency
• Restricts access from unqualified personnel
• Protected from exposure to freezing weather
• Provide adequate clearances for piping connections and service procedures

Connections

Pre-Installation Checks

Contents Under Pressure!
Failure to follow this safety precaution could release dangerous pressures which could result in death, serious injury, or property damage. Always operate within allowable temperature and pressure limits and only circulate approved fluid media through the heat exchanger.
Ensure the following before proceeding with installation :

• System fluid pressures are below the maximum allowable operating pressure of the unit
• Fluid temperatures of the system are above the minimum allowable temperature and below the maximum allowable temperature of the unit
• Fluids/chemicals flowing through the unit should be compatible with the plate and gasket materials
• Inspect the unit for visible signs of damage before filling and/or operating to avoid unnecessary leaks

Ensure the “A” or the compression dimension of the heat exchanger is within the limits described on the unit’s nameplate.

After locating and placing the unit and performing preinstallation checks, make your water connections.

Hazardous Pressures!
Failure to follow this safety precaution could release dangerous pressures which could result in death, serious injury, or property damage. Trane rental hose has a maximum allowable operating pressure of 150psi. For applications with higher pressures, hard piping must be used.
If using rental flexible hose, refer to CHS-SVX01*-EN for additional instruction on proper handling and use of the hoses and fittings. Rental hose has a maximum allowable operating pressure of 150 psi. If the heat exchanger is to be operated at pressures above 150 psi (but still below the maximum allowable operating pressure of the heat exchanger) then hard piping must be used.

Make piping connections as follows:

• The Hot Water Inlet connects to the water line that carries hot water away from the process that needs to be cooled.
• The Hot Water Outlet connects to the water line that carries cooled water to the process that needs to be cooled.
• The Cold Water Inlet connects to the outlet of the fluid cooler (chiller/cooling tower/etc).
• The Cold Water Outlet connects to the inlet of the fluid cooler.

The rental heat exchanger itself is built with permanent pipe connections that are ANSI 300 Flange style. For convenient use with rental hose, the unit is converted to grooved connections and ships with a short section of pipe on each inlet and outlet of the heat exchanger. The short sections of pipe are each fitted with pressure and temperature gauges

Hazardous Chemicals!
Failure to follow this safety precaution could result in death, serious injury, or property damage. Handle chemical carefully and avoid contact with skin. ALWAYS wear Personal Protective Equipment (PPE) including goggles or face shield, chemical resistant gloves, boots, apron or suit as required. For personal safety refer to the cleaning agent manufacturer’s Materials Safety Data Sheet and follow all recommended safe handling practices.
When filling the system, ensure there are protections in place to prevent chemical spills that may cause personal, property, or environmental damage.
: Clogging
Failure to do so could cause premature clogging of the heat exchanger. It is recommended that a bypass or strainer is used when first flushing the system loop.
If the system needs to be flushed before operation, it is recommended that this is done with the heat exchanger bypassed to avoid clogging due to debris in the flow media.
Avoid rapid flow/pressure changes during startup. Any valves used should be opened slowly to avoid a “water hammer” effect.

Freeze Protection

****Freeze Hazard!
Failure to do so could result in vessel rupture and sudden release of contents under high pressure and could result in death or serious injury or possible equipment or property damage. The heat exchanger must be protected from freezes due to fluid temperatures and/or ambient conditions.
If operating the heat exchanger with below-freezing fluid temperatures, the user is responsible for selecting an approved anti-freeze solution and applying it in proper concentration to prevent damage to the heat exchanger.
If the heat exchanger will be exposed to freezing ambient temperatures, the user is responsible for freeze protection of the unit. Heating blankets or heat tracing and insulation may be used, but in the event of a power outage, the heat exchanger will be unprotected. For this reason it is highly recommended that the user selects an approved antifreeze solution and applies it in proper concentration to protect against the lowest expected ambient temperatures.

Decommission

Hazardous Pressures!
Failure to follow this safety precaution could release dangerous pressures which could result in death, serious injury, or property damage. Ensure the system has been depressurized before loosening any piping connections.
Hazardous Chemicals!
Failure to follow this safety precaution could result in death, serious injury, or property damage. Handle chemical carefully and avoid contact with skin. ALWAYS wear Personal Protective Equipment (PPE) including goggles or face shield, chemical resistant gloves, boots, apron or suit as required. For personal safety refer to the cleaning agent manufacturer’s Materials Safety Data Sheet and follow all recommended safe handling practices.
Before loosening piping connections, the system should be de-pressurized. Before draining the system, ensure that there are property, environmental, and personal protections in place to prevent damage due to chemical spills. Also ensure that disposal and/or containment of any chemical solutions is done properly and within the guidelines of any environmental laws in the area.
If the flange-to-groove adapters and short sections of grooved pipe have been uninstalled to accommodate flanged connections, re-install them onto the heat exchanger before returning the equipment.
If any chemical solutions, hazardous or not, were used during operation of the heat exchanger, the user must flush these materials out before returning. Contact Trane Rental Services for assistance in identifying an appropriate cleaning solution based on the chemical solution that has been circulated through the unit.
