Success story
The Courtauld Gallery – London
Humidification Solution and high
level of service support
UE008WLC01 Steam Humidifiers
Indoor air quality control is a fundamental, albeit often overlooked, factor
in the museums. The installation of CAREL Isothermal humidification systems
and Reverse Osmosis water treatment, configured to perfectly match the air
handling units through adaptation of CAREL’s technologies, has made humidity
management especially efficient. As a result, the highest standards in terms
of indoor air quality and service continuity required of these systems has
been met, regardless of the different needs of the environments where the air
handling units are installed.
Where
The Courtauld Institute of Art
Somerset House
Strand
London, WC2R 0RN
It houses the collection of The Samuel Courtauld Trust and operates as an
integral part of The Courtauld Institute of Art.
What
Planned Preventive Maintenance contract for seven CAREL heaterSteam
humidifiers, three Water Treatment systems models various Compact WTS and one
model WTS Large in order to ensure the correct environmental humidity control
specification.
Why
To grant the continuity of humidifiers operativity and provide a high service
level to the museum.
The CAREL proposal
The Courtauld Gallery is located at Somerset House, London. It is world
renowned for it’s displays of priceless paintings and works of art. Humidity
levels are critical, 50% relative Humidity (r.H.) must be constantly
maintained, and are closely monitored to protect the exhibits.
CAREL was tasked to provide close control humidification for the galleries.
Resistive humidifiers model heaterSteam with steam lances injecting steam into
Air Handling Unit’s coupled with Water Treatment System equipment was proposed
to the client. This combination of equipment generates a very impressive +/-1
% controllability.
Isothermal technology
“heaterSteam”
Electric heater humidification is the ideal solution to meet the following
requirements:
- use of steam;
- exceptional relative humidity control performance (±1%);
- a functional solution that is independent of feedwater characteristics;
- service continuity.
Technology: the air humidification technologies currently on the market
have made a significant step forwards with the upgraded CAREL heaterSteam
range of high-precision heater humidifiers, available in models from 2 to 80
kg/h. The product has been overhauled in every aspect, from its mechanical
components to the new electronic controller with graphic interface based on
the c.pCO platform. The new software functions make heaterSteam even more
reliable and versatile, while its extensive connectivity allows seamless
communication with any BMS system.
Steam distribution: heaterSteam can be used for humidification in the air
duct, if used with the stainless steel distributors, or alternatively directly
in the room, in combination with CAREL steam blowers.
Operating principle: heat is transferred to the water via the completely
immersed heating elements. The solid state relays, managed by the PWM system
with built-in humidity or temperature controller, modulate the quantity of
heat delivered to the water so as to precisely control steam flowrate. The
heating elements are made from titanium or Incoloy® 825, materials that are
highly corrosion resistant, and feature an embedded PTC sensor to protect
against overheating, for maximum reliability. These features mean heaterSteam
is independent of feedwater quality, while ensuring very precise flow-rate
modulation (±1% RH around the set point.
Specific features:
- patented AFS system (Anti Foaming System) that detects and manages foam to prevent droplets of water being carried by the steam;
- cylinders with plug-in power connectors for easy, quick and risk-free maintenance;
- quick start-up and a wide range of feedwater conductivity, for higher performance;
- built-in conductivity sensor and control software to optimise energy efficiency and operating life, with constant performance over the life of the cylinder;
- modulating limit probe for maximum safety in AHUs/ducts.
Water Treatment System technology
Supplied with mains water, it generates demineralised water with
characteristics that make it ideal for use with humidifiers and evaporative
cooling systems. For heater or gas-fired steam humidifiers, the treatment
minimises the buildup of mineral salts and fouling in the heat exchangers,
increasing their working life: maintenance is reduced which inturn increases
efficiency and optimum performance of the humidifiers.
Reverse Osmosis: It is a technique by which the water to be purified is
pumped at high pressure through a semipermeable membrane, whose pores measure
less than 0.001 μm in diameter: most of the dissolved ions are filtered by the
membrane, producing extremely pure water. The removal of minerals, measured as
a percentage of the original content, varies from 95% to 99% and even higher.
Automatic operation and limited running costs extend the use of this
technology, with undisputed advantages.
Available models:
- WTS Compact: developed for treating water intended for use with humiSonic and heaterSteam humidifiers and small atomisers.
- WTS Large: is suitable for higher-capacity steam humidifiers, such as gaSteam, and for the entire range of adiabatic devices.

CAREL’s simplified maintenance proposal
CAREL UK originally supplied replacement humidifiers and associated Water
Treatment equipment in 2019 to maintain and control humidity levels in the Art
Galleries, each unit is installed on air handling unit equipment located in
various plant rooms throughout the building. The Humidifier Planned Preventive
Maintenance contract was awarded to CAREL UK in 2021, the client’s main reason
for mobilising CAREL Services was mainly because they demonstrated extensive
knowledge, experience, trust and support. The remit was simple, to maintain
the CAREL heaterSteams and Water Treatment System equipment to a very high
standard that is expected from a global leader in humidification.
Activities involved
Attention to detail when servicing, forward PPM planning, polite,
knowledgable, skilled, punctual engineers and the flexibility to attend site
at short notice are just some of the requirements set out by the client. The
critical application meant that if any fluctuations in humidity control
occurred then prompt action can be called upon. The client opted for six
maintenance visits per year, this enabled CAREL to structure the maintenance
to give full support throughout the year. Based on the professional services
provided the annual maintenance contract has been renewed year on year.
Services organisation
CAREL UK service is second to none, the service department utilises an in-
house service team and service partner network to ensure that humidifiers run
at their optimum levels, with good levels of service stock available at short
notice. Our service engineers are experienced and knowledgeable in all aspects
of humidification and water treatment and are certified and constantly updated
to analyse the general conditions of units and components and implement
corrective or preventive actions to keep them working efficiently to protect
the customer’s investments.

Conclusions
At the end of the project, the customer achieved the following results:
- guaranteed correct operation over time;
- protected performance;
- extended product life;
- faster resumption of operation;
- reduced management costs for unexpected events;
- guaranteed service times;
- CAREL genuine original spare parts.
