PERFORMANCE ANDUSES of Defrost Heater for Cold Stores

■ Defrosting electric heating pipes are newly designed to solve the problem of bad refrigeration effect caused by difficult defrosting in various freezers and refrigerating cabinets.

It adopts the stainless steel pipe as the base materials.Two terminals can be treated with special techniques to form any shape to theuser's requirements.It can be convenientlyinlaidin the sheet of the coolfan condenser,the bottom electrically-controlled defrosting in the water collection tray.It has the features such as the fine defrosting result,high electrical strength,nice insulating resistance,anti-corrosion and ageing,strong overload capacity,little currentleakage,

good stability and reliability,long service life atc.Among them,it brings about the secure and reliable sealing and damp-proofness to the terminals.It gats the national patent.It is higher than JB/T2379-93 standard for the product quality index and technical targets.◎Damp insulation resistance≥200M Ω2

◎Insulation resistance after wet & hot test≥30M Ω◎Damp leakage current≤ 0.5mA◎Surface electric density≤3.5W/CM

○Operating temperature:150"℃ ( max.use temperature:300"℃)

Drain electric heating flexible wire product performance and use

Drain electric heating flexible wire device is a drain pipe purpose electric heating flexible wire which has been used in the freezer,refrigeration cabinet etc. It is originalin China.It has the sound damp-proofness,anti-frozen,heat-resistant, anti-corrosion and ageing properties.It is widely applicable for operation in the lowtemperature and damp environments It has the long service life,high insulation resistance,little leakage current.Voltage withstand≥180oV.Damp insulation resistance≥100MΩ.Insulation resistance after wet &hot test ≥10MΩ.Damp leakage current ≤0.3mA.Service temperature≤60°℃C.It is safe and reliable in the using process.

■ Properties and uses of the energy-saving electric appliance

Energy-saving electric appliance is the national patent product which has been researched into and developed by our company.It thoroughly overcomes the disadvantages of the previous electric heaters which do not have certain pressure, heat exchange,over-large heat loss,easy oxidation to the bare resistance wire,inconvenient renewal etc in the mould heating.Energy-saving electric heateradopts the metal tubular electric heating assembly which have been directly poured into the cast iron and form the composite type novelenergy-saving electric heater through the processing.

Advantages:High heat radiance of cast iron,even heat staoility,fine heat conductivity.It enhances 40-45% of the utilization ratio of heat energy with the outstanding energy-saving.Tubularelectric heat assembly have been founded in the metal body without shif.It resists the impact and vibration.Underthe high temperature workconditions,it is of the high voltage-withstand intensity,the long service life,the simple structure.It can be made into variousshapes and specifications. It is of the direct heating,safe and reliable use,convenient installation or renewal.

Freezer defrost heaters is newly designed to solve the problem of bad refrigeration effect caused by difficult defrosting in various freezers and refrigerator cabinets. The defrost heater is made of stainless steel tube. According to the user's requirements, both ends can be bent into any shape.

It can be conveniently inland in the sheet of the cool fan and condenser, the bottom electrically-controlled defrosting in the water collection tray. It has the features such as the fine defrosting result, high electrical strength, nice insulating resistance, anti-corrosion and ageing, strong overload capacity, little current leakage, good stability and reliability, long service life, ect. The Rubber head won the national patent. It is high level secure, reliable sealing and damp-proofing.
