Reventon HC Prestige Set (water-to-air heater + swivel console + programmable HMI controller) HMI BMS HC20-3S Set, 1.5 – 29.7 kW*

HC Prestige Set (water-to-air heater + swivel console + programmable HMI controller) HMI BMS HC20-3S Set

The HC-3S series water-to-air heater is designed for industrial buildings with a central heating system. The unit is fitted with an EPP (expanded polypropylene) casing, making it suitable for use in harsh environments, such as those with high humidity. A further advantage of the EPP casing is that it dampens the unit’s operating noise, thereby ensuring quiet operation. The casing is made from environmentally friendly material that is 100% recyclable.

Areas of application:

The HC-3S water-air heater successfully provides thermal comfort in:

• Production halls
• Storage areas
• Shopping centres
• Car workshops
• Garages
• Greenhouses

HC Swivel Bracket 20-45:

The swivel bracket is a mounting component for HC series air heaters. It allows the unit to be rotated horizontally to suit the user’s current requirements.

Programmable HMI BMS controller:

The controller is used to control units with three-speed fan motors. The controller automatically regulates the unit’s operation in accordance with the set programme (the desired air temperature). It offers the option of connecting an external temperature sensor (included in the scope of delivery). The unit also controls the operation of the actuators fitted to the control valve. It features the Modbus communication protocol, which enables the controller to be integrated into the building management system (BMS).
