High-temperature air-to-water heat pump: NEROMAX
ETT has developed a range of latest-generation heat pumps: NEROMAX. NEROMAX is a thermodynamic system for producing hot or cold water.
The ETT packaged unit is delivered ready to operate. Its full aluminium structure (frame and casing), ensures an excellent corrosion protection (20-year anti-corrosion guarantee). The ETT unit can be installed either at ground level or on a roof.
Description
NEROMAX is guaranteed for 20 years against corrosion
This new ETT unit is designed to meet all of the requirements of a building:
- Heating
- Cooling
- Domestic hot water (DHW) via a primary network
The unit operates as a heat pump:
- Treated fluids: cold and hot water
- Rejection: outside air
- System: 2 pipes
The NEROMAX module offers several operating modes:
- Hot water mode:maintains the temperature of hot water networks using the thermodynamic system (up to 70°C with the NEROMAX HT version).
- Cooling mode:maintains the temperature of the cold water network using the thermodynamic system.This mode is not available on the NEROMAX HT version.
- Compact version:Each NEROMAX and NEROMAX HT machine is available in a “COMPACT “ version for projects requiring shorter unit lengths. Hydraulic options are not available on “ COMPACT “ versions.
