Overview of the Cryogenic -80°C to 200°C Chiller Heater System
Product Model: PLYY-80-100
Temperature Control Range: -80-200℃
For use with a 100L jacketed reactor, heating power 7.5KW, cooling power 7.5KW.
The high- and low-temperature cycling unit is also known as a 'high-and-low-temperature integrated machine,' 'cold-and-hot integrated machine,' or 'heating and cooling circulator.'
The ultra-low temperature heating circulation unit is primarily used to provide an ultra-low temperature circulating cooling liquid for the jacket of reaction vessels that require low-temperature reactions, thereby maintaining low-temperature conditions during operation. It can be used in conjunction with double-layer glass reactors of 20L, 50L, 100L, and other capacities, cooling the reaction vessel contents down to -70℃ or -80℃.
● Equipped with microcomputer control and a fully digital Chinese display for convenient operation. The temperature display uses high-brightness LEDs. Features include high- and low-pressure protection, overload protection, and overcurrent protection.
● Environmentally friendly, fluorine-free refrigerant that complies with EU and national standards.
● The refrigeration system components—including the compressor, oil separator, solenoid valve, and expansion valve—are all imported brands.
● The evaporator is a fully brazed plate heat exchanger.
● A specially designed low-temperature circulating pump ensures no leakage or stalling even under low-temperature operating conditions.
● The circulation system adopts a closed-loop design, providing volatile-free protection for experimental personnel’s health.
● The liquid storage tank and the heat-transfer medium are both made of 304 stainless steel, offering excellent corrosion resistance.
● The entire machine is stable and reliable, capable of meeting the demand for process cooling sources in continuous production lasting more than 24 hours.
● The main unit is cooled by air.
● The casing features electrostatic powder coating, offering excellent corrosion resistance.
Typical applications of the refrigeration, heating, and temperature control system

Closed Loop
The entire system is fully sealed. At high temperatures, there will be no oil mist; at low temperatures, it will not absorb moisture from the air. During operation, the system will not experience pressure increases due to high temperatures, and at low temperatures, the heat transfer medium will be automatically replenished.
