Carel’s Latest Addition to the Electric Resistive Humidifier Lineup

The new heaterSteam range employs the features of the latest generation of Carel’s electronic controllers and uses Titanium heaters, thus representing a continuity solution in the development of heater humidifiers.

heaterSteam is the ideal solution for applications needing superior performance for controlling air humidity very accurately (±l%RH), mission critical service continuity using all types of feed water and ensuring connectivity tools able to anticipate remote management requirements.







The heating elements are made in titanium, designed to work with extreme aggressive water such as demineralized/deionized water with conductivity below 1 IJS/cm and softened water of up to 0° fH.

The reliability of the titanium in combination with the overheating protection (heaterSteam is the only humidifier on the market with heaters featuring temperature sensors) makes Carel solution ideal for applications where service continuity is essential such clean rooms, hospitals and museums.

In particular, it can work with treated water of any quality, including ultra-pure demineralized water, since titanium heating elements are not at risk of corrosion. This type of water, purified to an extreme, is used frequently in the pharmaceutical field and, due to its organoleptic characteristics, can be aggressive towards the materials normally used inside humidifiers.

The over temperature protection (unique to the market) and patented Anti-Foaming System are a further guarantee of the application’s reliability, whereas the modulating limit sensor prevents condensation from forming without compromising the accuracy of the system.


heaterSteam titanium is the solution to relative air humidity control accuracy requirements. By using demineralized water Carel’s heater humidifier can meet humidity requirements with ±1% accuracy.

The production capacity modulation range from 0 to 100% in combination with the possibility of pre-heating the water inside the boiler means that heaterSteam is ready to respond to humidity requirements.


Another element that sets heaterSteam apart from the competitors is undoubtedly the state-of-the-art electronic controller. The Modbus and Bacnet communication protocols are available as standard on both the BMS serial output and Ethernet. The Carel communication protocol is available only through the BMS output. No additional electronic boards are therefore required.

The Ethernet connection can also be used to access the integrated web server on the local network. It is therefore possible to configure and monitor the units directly from a PC using a standard web browser.

heaterSteam is also tERA ready. Enabling the service via Ethernet connection permits remote monitoring and interaction with the unit.


heaterSteam process is the ideal solution for applications where reliability and flexible operation need to be combined with feed water characteristics that are not always controlled.


Thanks to the Master/Slave “Endurance” function, the capacity of the humidifiers installed can be expanded without complicating the system. The “Endurance “function allows heaterSteam to control up to 19 further units via Ethernet.


The electronic controller exploits the mechanical characteristics of the heaters to perform thermal shock cycles in complete safety in order to remove any lime scale deposits from the heating elements. This results in longer routine maintenance intervals and greater cleanliness of the unit.


For installations where it is not possible to use standard wired sensors, when modifying existing installations for example, wireless sensors can be used. The connection is made via Carel Access Point using a maximum of 4 wireless sensors. The installation type is indicated in the figure below (in the case of 4 wireless room sensors)

iAIRE Refrigeration & Reheat Controls

RAWAL device is a hot gas bypass valve with a de-superheating chamber. Instead of feeding hot gas from compressor discharge directly to the evaporator coil which raises evaporator temperature, reducing the coil’s capacity to remove moisture, the RAWAL valve mixes hot gas from the compressor discharge with liquid from the condensing coil in the de-superheating chamber and feeds that mixture back to the compressor suction. The valve works on suction pressure and is designed to maintain suction temperature at 40-45F. As the cooling load reduces the suction, pressure (and temperature) drop due to the reduction in heat transferred at the evaporator coil. The RAWAL valve reacts by mixing hot gas and liquid in the de-superheating chamber and metering this back to the compressor suction line before a suction accumulator. This prevents liquid from slugging the compressor and allows the system to maintain a constant suction pressure under varying load conditions. This allows the compressor to operate normally and guarantees a cold evaporator temperature at a low load condition. Low load conditions are often accompanied by high relative humidity. The cold evaporator maximizes moisture removal and modulating hot gas reheat is used to control the leaving air temperature.

Benefits associated with the iAIRE system using the RAWAL APR                                   valve for refrigeration capacity control include:

  • Constant compressor suction pressure/temperature providing for stable operation during a wide range of load conditions
  • Guaranteed cold evaporator temperature at low load conditions for maximum moisture removal
  • Fluctuations in compressor head pressure under varying ambient conditions have minimal impact on system operation due to constant suction pressure
  • System operation at normal pressures/temperatures                                                     simplify maintenance and troubleshooting

Why Install an Expansion Tank with Every Water Heater Installation?

Installing a thermal expansion tank with a new water heater has become increasingly important. Most cities nowadays have check valves in their water meters which prevent the home’s water from going back into the public water system. While this process poses a health benefit, it creates a problem for the domestic water system.

The check valves make the domestic water system in a house a “closed system.” This means that when the water in the water heater is heated, it expands but has nowhere to go. It therefore increases the pressure in the domestic water system, potentially causing damage and leaks to the system. See attached brochure from Bradford White for more details.

There exists a simple solution: to install a thermal expansion tank on the cold water inlet of the water heater. Sizing is also simple: use a HWTX5 tank for 40 & 50 gallon water heaters. For water heaters above 50 gallons, use a HWTX12 tank. Expansion tanks are cost-effective and easy to install with a new water heater.
