Chilling & heating circulator

Chilling and heating circulator is designed on the base of circulating chiller and high temperature oil bath.

Product Features

Chilling and heating circulator is also known as High-Low Temperature Circulating Device, is composed of a refrigeration unit, heating unit, circulating system, and control system.

The entire circulating system utilizes a fully enclosed circulation with a liquid expansion container. The expansion container and liquid circulation are independent systems, where the expansion container is mechanically connected but does not participate in the liquid circulation. Even under high-temperature operation, the heat transfer medium in the expansion container does not exceed 50 degrees Celsius.

The entire liquid circulation operates as a closed system, ensuring no water vapor absorption during low-temperature operation and no oil mist generation during high-temperature operation, thus improving the lifespan of the heat transfer oil. With the same equipment and heat transfer medium, it can achieve continuous temperature control from -95 degrees Celsius to 350 degrees Celsius. The cooling capacity ranges from 1 kW to 100 kW, providing a wide selection range.

Features

  • Combined heating and cooling container with large heat exchange area for rapid temperature changes and reduced heat transfer oil demand.
  • High-temperature and high-pressure compressor technology for direct cooling from 350 degrees, improving cooling rate.
  • Safety features include self-diagnosis, overload protection, high-pressure switches, and high-temperature protection.
  • Temperature adaptive control with precise PID parameter adjustment for optimal temperature control.
  • PT100 temperature probe and correction loop for accurate temperature measurement and control.
  • Uses environmentally friendly refrigerants without CFC and HCFE.
  • Enables precise control of chemical reaction speed.
  • Liquid circulation pipeline and heating pipes made of industrial-grade stainless steel for durability.
  • Features scroll compressor and high-temperature-resistant circulating pump for reliable performance.
  • Utilizes solid-state relays for spark-free and noiseless operation.
  • Wide temperature ranges from -95 to 350 degrees with heating and cooling functions.
  • Displays set temperature, actual temperature, and temperature alarm value simultaneously.
  • Simple and efficient liquid filling process.
  • Rapid cooling from high temperatures and continuous temperature control from 350 degrees to -95 degrees.
  • Designed with high-quality stainless-steel wire-reinforced hoses and insulation covers for safe connections in high-temperature environments.

Application

The High-Low Temperature Circulating Device, namely Cooling and Heating Circulator is designed on the base of circulating chiller and high temperature oil bath. It is usually used as an ancillary equipment for jacked glass reactor, molecular distillation, and rotary evaporator, supply low and high temperature reaction condition. Widely used Colleges and universities, environmental protection, biochemical, medical, chemical industry, scientific research, etc.

Sanitary grade of SUS304/SUS316L Stainless Steel Vendor: Shanghai Bao Steel Group Corporation or equivalent supplier.

In order to keep the raw materials organized and make sure proper material will be used, we insist asking the material vendor to provide original material test report. Also, we will do in-coming tests to ensure the material is qualified:

  • Metal spectrum analyzer
  • Thickness gauge
  • Roughness detector

All designing, manufacturing and inspection processes are performed according to GB150-1998. ISO9001 Quality Management System Standard will also be applied throughout the entire manufacture process.

Yes, with our certified workshop and excellent welding technics, we can provide you with high quality ASME or PED pressurized equipment.

As multiple tests and inspections are required, lead time of such equipment is longer than normal pressure equipment, it usually takes 18 to 20 weeks to finish.

Plasma welding machine imported from Germany will be used for tank longitude and girth welding and fillet welding to make sure the welding seam smooth and even.

Also, GTAW welding technology will be applied, inert gas concentration is 99.999%. Different welding wire ER316L or ER308 will be applied for different material of SS plate.

For particular circumstances, electric-arc welding will be applied. Welding material used for:

S304-S304: A102; S316L-S316L: A022; Different SS: A302.

Welding seam between jacket and vessel shall be NDT inspected according to JB4730-94 to ensure the impermeability and long service life.

For single tank, it takes around 3-5 weeks to deliver.

For integrated systems, it normally takes 18 to 20 weeks to deliver.

ASME/PED certified equipment will take 18 to 20 weeks

You are welcome to contact us for details if any needs.

Yes, customization order is acceptable.

You may send over the requirements, we will realize your design and provide you with the most cost-efficiency solutions.

Plastic wrap film should be applied around the entire equipment.

Electrical parts should be disassembled and packed in crates if possible, otherwise it should be fully protected from water or any kind of potential damage in shipping.

Tank will be put down and sitting on a CS frame support, steel wire will be used for fasten tank to support. Rubber should be applied to where steel wire is touching the equipment.

When fixing the equipment in container, multiple fixing belts and/or steel wires should be used to make sure no movement of equipment.

should be used to make sure no movement of equipment

Yes, we will.

Equipment will be thoroughly washed before packing. Water used for washing should not have chloridion content more than 25mg/L to avoid damage of stainless-steel surface. Water stains must be cleaned once washing is finished.

Normally we will ship the equipment by sea due to the weight of it.

Air shipping is also an option, but it will cost more.

It depends on your choice.
