Circulation heater refers to the ability to provide refrigeration and heating at the same time, also known as refrigeration and heating systems, which can provide a wide temperature range, and the medium can use heat transfer oil, ethylene glycol solution, water, ethanol, etc. as required.
1. What are the characteristics of the circulation heater?
The circulation heater is composed of refrigeration system, electric heating, circulation pump, expansion tank, PLC controller, etc. The components are all brand-name, with strong reliability, and can realize a wide range of temperature control from a low temperature of -120°C to a high temperature of 350°C , high temperature, no oil fume, low temperature, no condensation, high degree of customization, and can be customized according to the application characteristics of different industries.
2. How to choose the type of circulation heater?
The selection of the circulation heater generally needs to provide the application industry, process requirements, site environment, etc. For example, chemical and pharmaceutical industries need to control the temperature of the reactor, and the process requirements of the materials need to be provided: temperature range, temperature control accuracy, reactor specifications, temperature Variable speed, whether explosion-proof is required, whether the equipment is air-cooled or water-cooled, etc., we have rich supporting experience in many industries, and can quickly match the equipment to meet the needs according to the content provided.
3. What are the environmental requirements of the circulation heater?
The design of the circulation heater is mainly for indoor applications. If it is placed outdoors, it must be explained in advance, so as to design and handle different waterproof and dustproof levels according to the site environment; the circulation heater is generally divided into water-cooled and air-cooled. Air-cooled equipment requires good ventilation and heat dissipation on site. , Water cooling needs to be configured with circulating water or chilled water; if large equipment is placed on the floor, load bearing needs to be considered.
4. What are the advantages of circulation heater?
The circulation heater is mainly used to control the oil temperature of the reactor jacket, and at the same time monitor the return oil temperature, which can directly control the temperature of the material in the reactor, or switch to control the oil temperature of the reactor jacket. The response is fast and can meet the process of the material in the reactor. accurate temperature control
5. What is the difference between explosion-proof and conventional circulation heater?
For use in hazardous gas areas, only circulation heaters that meet explosion-proof standards can be used; common explosion-proof standards include ExdIICT4, ExdIIBT4, positive pressure explosion-proof, etc., and the motors, electrical appliances, sensors, and explosion-proof cabinets used in explosion-proof circulation heaters must meet the requirements. corresponding standard. In comparison, the size of explosion-proof equipment will be larger, the cost will be higher, and the delivery cycle will be relatively longer.
