For direct-expansion applications, evaporator type, superheat control, oil return, refrigerant charge and local ammonia-safety requirements must be engineered for the complete system.
Typical Applications
Food, Dairy & Beverage
Process chilled water, glycol cooling, cold-storage utilities, production-area cooling and refrigeration duties where ammonia is appropriate to the project and local regulations.
Cold Storage & Industrial Process Cooling
Central glycol systems, low-temperature process loads and refrigeration plants requiring packaged outdoor equipment with reduced refrigerant charge and a compact plant footprint.
Heat-Recovery Projects
Oil heat recovery, condenser heat recovery and hot-water integration can be reviewed where useful heating demand overlaps the refrigeration load.
Replacement & New Projects
New installations and packaged replacements can be reviewed from required cooling duty, glycol conditions, ambient design temperature, available electrical supply and project safety requirements.
What to Send for Selection
- Required cooling capacity and whether the duty is medium-temperature glycol, low-temperature glycol or direct expansion.
- Glycol type/concentration and inlet/outlet temperatures, or required evaporating temperature for DX duty.
- Design outdoor ambient, project country and installation elevation.
- Electrical supply, allowable current or starting constraints and preferred redundancy.
- Heat-recovery requirement, if any: hot-water flow and target inlet/outlet temperature.
- Applicable ammonia safety code, machinery or pressure-vessel requirements, access and installation constraints.
