ACV EVO S 40kW Plate Heat Exchanger Kits Instructions
INTRODUCTION
This technical data contains information for dimensioning & assembly of a cascade system kit for the Evo S.
GENERAL DESCRIPTION OF FRAME & HEADER KITS
A requirement to spread the total required heat output over several boilers
can be accommodated by the use of the Evo S multiple boiler frame & header kit
options.
GENERAL DESCRIPTION OF CASCADE SYSTEMS
FRAME AND HEADER KIT DESIGN OPTIONS
Note: All boilers need to be sized in accordance to the total required
heat load and the modulation capabilities of the appliances.

Note: The total system output must not exceed the Plate Heat Exchanger kW Rating.
One Plate Heat Exchanger Kit required per cascade.
Refer to the Boiler Installation, Commissioning and Servicing Instructions, and the Navistem B3100 manual for cascade options.
SYSTEM SEPARATION: LOW LOSS HEADER & PLATE HEAT EXCHANGER
A low loss header or plate heat exchanger allows flow separation within a heating system.
This allows two flow circuits to operate with their own flow and pressure drop environments whilst effectively transferring heat to its adjoined water circuit.
This enables the modern high resistant, high efficiency boilers to operate under their optimum conditions, while the main heating circuit operates to its own controlled optimum requirements. Hamworthy’s brazed plate heat exchangers ensure optimum heat transfer efficiency and low resistance within a compact footprint. The heat exchanger allows hydraulic segregation between the boiler primary and secondary heating circuits. Used in conjunction with ACV’s 40-70 kW and 80-150 kW frame and header kits covering duties from 60kW to 900kW.
The design is based on standard components and a modular brazed concept. Each unit is manufactured to the highest standard and part of the AHRI certified program that ensures thermal performance in accordance with the product specifications.
Benefits
- Compact design
- No gaskets
- Easy install with ACV’s Frame and Header Kits
- Low maintenance/ self-cleaning
- All units are pressure tested
ASSEMBLY
The frames must be located in a suitable place that affords a flat and level
floor-area of suitable load bearing capacity. Care must be taken when locating
the frames that space is available for the servicing, installation and
maintenance of the appliance and all of the associated connections and
equipment. (See appliance manuals)
When using multiple frames they must be bolted together and where necessary secured to the floor.
SAFE HANDLING
Installation may require 2 or more operatives to move it to its installation site, remove it from its packaging base and during movement into its installation location. Manoeuvring may include the use of a sack truck and involve lifting, pushing and pulling. Caution should be exercised during these operations
Operatives should be knowledgeable in handling techniques when performing these tasks and the following precautions should be considered:
- Be physically capable
- Use personal protective equipment as appropriate, e.g. gloves, safety footwear
During all manoeuvres and handling actions, every attempt should be made to ensure the following unless unavoidable and/or the weight is light.
- Keep back straight
- Avoid twisting at the waist
- Avoid upper body/top heavy bending
- Always grip with the palm of the hand
- Use designated hand holds
- Keep load as close to the body as possible
- Always use assistance if required
KIT CONTENTS
PHEX kit comprises brazed heat exchanger, pipe spools, flanges and fixings to
enable direct assembly on to frame and header kit.
