HLTZ Series Hydrogen Cooling Chiller
APPLICATIONS
Adopt positive pressure explosion-proof system, the positive pressure system has a built-in thermostat to ensure that the system environment is maintained at normal temperature. Hydrogen passes through the internal high-pressure heat exchanger, and the refrigeration system directly exchanges heat with hydrogen through the refrigerant to achieve efficient heat exchange and temperature control; compared with traditional antifreeze or other fluids and hydrogen heat exchange, this equipment uses the medium as the refrigeration system refrigerant (phase change heat), which is more energy efficient.
