SUNDIZ8 -80°C ~ +250°C Frequency Conversion Heater & Chiller System

Product Description Custom Design

This series of products adopts variable frequency control for their refrigeration and circulation systems, compared to the old product, it saves more than 20% energy, reduces noise by more than 5 decibels, and has a lower starting current.

By increasing the frequency, increasing the cooling power, and improving the cooling rate, the frequency conversion control of the circulating pump can be enhanced.

Cooling capacity kW @	250℃	3.5	5.5	7.5	15	20
	20℃	3.5	5.5	7.5	15	20
	-60℃	1.3	1.8	3	5.5	8
	-75℃	0.4	0.6	1	1.8	2.7
Medium temperature control accuracy		±0.1℃	±0.1℃	±0.1℃	±0.1℃	±0.1℃
Process temperature control accuracy		±0.3℃	±0.3℃	±0.3℃	±0.3℃	±0.3℃
Pump flow & pressure max		35L/min	50L/min	100L/min	150L/min	250L/min
		2bar	2bar	2bar	2.5bar	2.5bar
Refrigerant		Primary R-404A + Secondary R508B
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.
