The main applications are flammable and explosive and other special places. The output power ranges from 10HP-200HP. Can be customized according to customer requirements. Each component of the chiller is manufactured in accordance with national explosion-proof standards. Explosion-proof and anti-corrosion master controller is based on GB3836.1-2000 "General requirements for electrical equipment for explosive gas environments", GB3836.2-2000 "Explosion-proof type" d "for electrical equipment for explosive gas environments" and GB3836. 3-2000 "Explosiveness It is designed and manufactured according to the regulations of safety equipment "e" for gas environment. To meet the special requirements of customers.
The normal temperature water is cooled to a certain temperature by the chiller compressor to strengthen the cooling mold or machine. It is used as a single machine. The heat dissipation device is a built-in fan. There are mainly three interconnected systems: refrigerant circulation system, water circulation system, and electrical appliances. Automatic control system.
Refrigerant circulation system:
The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates to a gaseous state, and is then sucked in and compressed by the compressor (pressure and temperature increase) ), The gaseous refrigerant absorbs heat through the condenser and condenses into a liquid. After throttling through an expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.
water circulatory system:
The water pump is responsible for pumping water from the water tank to the equipment that the user needs to cool. The frozen water takes the heat away and the temperature rises before returning to the freezing water tank.
Electrical automatic control system:
Including power section and automatic control section.
The power supply part supplies power to the compressor, fan, water pump, etc. through the contactor.
The automatic control part includes the functions of temperature controller, pressure protection, time delay, relay, overload protection, etc. to achieve automatic start, stop and protection of the water temperature.
Energy saving
The unit uses high-quality imported twin-screw compressors, whose operating components are only 1/10 of the reciprocating compressors, and the vibration is 1/5 of the reciprocating compressors, without foundation fixation. The failure rate is only 1/10 of that of reciprocating compressors, and the control devices of world-class brands ensure that the unit can run safely and stably for a long time.
The screw compressor has a partial load function. Through the combination of multiple heads and PLC control technology, the unit can achieve the best energy efficiency ratio at full load or partial load, which significantly reduces your operating costs. We can provide four-stage (25%, 50%, 75%, 100%) and stepless energy adjustment methods for you to choose from.
Safety
The unit provides complete protection from the refrigerant system, electrical system to the water system, which fully guarantees the safe and normal operation of the unit. The compressor motor is protected from overheating, overcurrent, abnormal phase sequence, low oil level, low pressure and high pressure.
Efficient
The unit adopts a compressor with higher efficiency than the reciprocating compressor, and combined with the use of high-efficiency strengthened heat exchangers, the unit has a strong applicability and high efficiency.
flexible
Through the use of various compressors, the unit can provide various models from 40-460RT for you to choose, and one of them can meet your needs. We can also customize it for you according to your requirements.
Convenience
The unit adopts advanced PLC control technology, which truly realizes "one-button startup" and fully automatic operation. No human intervention is required.
After sales service
The warranty period is 12 months, free maintenance during the warranty period, only the material cost fee is charged outside the warranty period, and lifetime maintenance.
