It has low power and can defrost or heat in the refrigerator and expositing cabinet . both the ends of the heater adopt the imported resin glue and vulcanizate for seal ment and high ni - cr stainless steel as the case . it has good corrosive resisting performance and the insulation resistance is still more than 1000 after immersing in the water and being electrified for a long time 本加热器的特点为表面功率较小，在冰箱，展示柜中起加热化霜作用。电热管两端采用进口树脂胶及硫化橡胶封口，外壳采用高镍铬不锈钢，具有很好的耐腐蚀性能产品经长时间浸入水中通电试验，其绝缘电阻仍1000m 。
