Hot water and cold water generator
The hot & cold water generator is designed for hydraulic test benches, offering performance suitable for a variety of industrial applications. It is available in three thermal power configurations: 15 kW, 25 kW and 35 kW, for heating and cooling. With a continuous mixed water flow rate of 14 to 34 liters per minute, depending on the power selected, it ensures precise regulation with a tolerance of ±0.3°C. The system is equipped with a 600-liter hot water tank 600-liter hot water, and a 400-liter chilled water reserve tank. It also includes an anti-legionella system, automatic filling and automatic balancing.

Characteristics of hot and cold water generators
The hot and cold water generator regulates the temperature of a hot water tank and a cold water tank to supply hot and cold water to tap test benches, all in a closed circuit.
Equipped with a heating and cooling system, this generator can supply, continuously and in a closed circuit, a total mixed flow of 14, 24 or 34 l/min with a deltaT of 50°C.
Thanks to its energy recovery system, this generator provides a total thermal output (heating + cooling) approximately 2 times the electrical power consumed.
Coupled with benches equipped with hot and cold water distributors, energy consumption can be greatly reduced when the taps tested are not in the mixing position (50% hot 50% cold).
Operating mode
Discover how our hot and cold water generator works
A tank of chilled water, used as a cold reserve, is cooled by a heat pump. This heat pump transfers some of the calories “pumped” from the cold store to the hot water tank.
The chilled water tank is controlled by a servo-controlled exchange with the chilled water tank.
The hot water tank is regulated by an electric resistance.
The surplus heat (the part not recovered by the heat pump) is evacuated by a unit heater, which can be remote from the generator.
All fluids are circulated by speed-controlled centrifugal pumps.
The tanks are made of double-skinned stainless steel with polyurethane insulation.
Each tank is equipped with several temperature sensors to measure any temperature stratification (water colder at the bottom, warmer at the top) and, in this case, trigger automatic mixing.
The whole system is controlled by a PC equipped with a program ensuring temperature regulation to ± 0.3°C whatever the flow rate, while managing tank level safety devices, automatic tank balancing, etc.
Advantages of the WaterBank – Hot and Cold Water Generator
Energy saving
Energy recovery using a heat pump.
PC control system
The PC is equipped with a program for temperature control to +/- 0.2°C, regardless of flow rate.
