TBEX series — explosion-proof type oil chiller

TOBEL self-developed oil chiller utilizes forced air-conditioning cooling to control the oil temperature of mechanical equipment at constant temperature(such as hydraulic oil and lubricating oil).

Low temperature and low pressure liquid refrigerant exchanges heat with the oil in the evaporator, and evaporates into low temperature and low pressure gas. The temperature of refrigerant remains unchanged during the evaporation process.Then gas refrigerant is compressed by the compressor and compressed into high temperature and high pressure gas. When gas refrigerant enters the condenser, it exchanges heat with the indoor air. The refrigerant releases heat and comes into high temperature and high pressure liquid, and goes into the expansion valve.Throttling is a rapid cooling process, the refrigerant returns to low temperature and low pressure liquid. This cycle is continuous, so the oil can be continuously cooled.

product details

Scope of application

Mainly used in coal, petroleum, chemical and other places containing flammable and explosive gases and dust.

Characteristic

The equipment can be explosion-proof of the whole machine or only the host, and the control system can be placed in the non explosion-proof area.
Fault alarm and self-alarm signal output can be linked with the host
All components of the chilling machine are manufactured according to national explosion-proof standards. The main explosion-proof and anti-corrosion controller is designed in accordance with electrical requirements for explosive gas environments.
In flammable and explosive special places, the operation of oil cooling unit is safe and reliable.
Meet the special requirements of customers according to the special conditions, such as chemical industry, textile industry, coal industry and so on.
