About Item
Defrost System & Humidity Control Maintenance ensures proper ice removal from evaporators and accurate humidity regulation inside agricultural cold storage facilities. This service prevents airflow blockage, protects produce quality, and maintains energy-efficient refrigeration performance.
Service Overview
In cold storage environments, moisture from stored produce and air circulation can condense and freeze on evaporator coils. Improper defrosting leads to ice buildup, reduced airflow, uneven cooling, and increased compressor load. At the same time, incorrect humidity levels can cause dehydration, mold growth, or chilling injury to agricultural produce.
Defrost System & Humidity Control Maintenance ensures both defrost mechanisms and humidity regulation systems function optimally to maintain stable storage conditions.
