System pressure display		The pressure of the refrigeration system and circulation system is detected by pressure sensors and displayed on the touch screen.
Controller		Siemens S7-1200PLC, fuzzy PID control algorithm, with process dynamic control algorithm
Temperature control		Heat transfer medium outlet temperature control mode
		External temperature sensor: (PT100 or 4-20mA or communication setting) Control mode (process dynamic control algorithm)
Programmable		25 programs can be knitted, each program can be edited with 85 steps
Communication Protocol		Ethernet interface TCP/IP protocol, RS485 interface MODBUS protocol
Internal temperature feedback		Equipment heat transfer medium outlet temperature, medium inlet temperature, refrigeration system condensation temperature, ambient temperature, compressor suction temperature, cooling water temperature (for water cooling equipment)
External temperature feedback		PT100 or 4～20mA or communication setting
Cascade control		The temperature difference between the thermal oil outlet temperature and the external temperature sensor can be set and controlled
Temperature difference control function		The temperature difference between the equipment inlet temperature and the outlet temperature can be set and controlled (to protect system safety)
Closed circulation system		The entire system is a fully enclosed system. There will be no oil mist at high temperatures and no absorption of moisture in the air at low temperatures. The system will not increase pressure due to high temperatures during operation, and will automatically replenish heat transfer media at low temperatures.
Heating		Refers to the maximum heating output power of the system (depending on the model)
		The heater has triple protection and independent temperature limiter to ensure the safety of the heating system
		Use a voltage regulator to control the heating output and reduce the heater output current in process temperature control
Cooling		It refers to the ability to take away heat at different temperatures (under ideal conditions). The actual working conditions need to consider the heat dissipation of the environment. Please enlarge it appropriately and take insulation measures.
External circulation pump flow & pressure		Brand magnetic drive variable frequency pump
compressor		Emerson, Mitsubishi and other inverter compressors
Frequency converter		ABB and other well-known brands
Evaporator		316L plate heat exchanger
Refrigeration accessories		Danfoss/Emerson accessories (drying filter, oil separator, high and low pressure protector, expansion valve)
Operation panel		Wuxi Guanya customized 7-inch color touch screen, temperature curve display, EXCEL data export
Safety protection		It has self-diagnosis function; phase sequence failure protector, refrigerator overload protection, overload relay, thermal protection device and other safety protection functions.
Refrigerant		R-404A / R507C Optional R448
Water cooled condenser		Standard plate heat exchanger
Casing material		Cold rolled steel plate spraying (standard color RaL7035)

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃[because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.

FLUID CIRCULATION CLOSED TEMPERATURE CONTROL

The fully enclosed pipeline design and high-efficiency plate heat exchanger reduce the demand for thermal fluid while improving the system’s heat utilization rate and achieving rapid temperature rise and fall. The thermal medium is in a closed system with an expansion container. The thermal medium in the expansion container does not participate in the circulation. Regardless of high or low temperatures, the expansion tank temperature is kept at room temperature to 60°C, effectively reducing the risk of the thermal medium absorbing moisture and volatilizing during operation.
