Pulse Of The Heat Exchanger

FROST FREE EVAPORATOR

At KRN Heat Exchanger & Refrigeration Ltd., we design and manufacture Frost-Free Evaporators that provide efficient cooling without ice build-up on the evaporator surface. Equipped with an integrated automatic defrost system, these units deliver consistent airflow and temperature control, ensuring better food preservation, energy savings, and maintenance-free operation.

Our frost-free evaporators are widely used in domestic refrigerators, commercial freezers, and cold rooms, where reliability, hygiene, and performance are critical.

Design & Construction

  • Tube Material: Aluminium Alloy grade AA1070,AA1060 and AA1050 for superior thermal conductivity
  • Fin Material: Aluminum fins for excellent heat transfer and corrosion resistance
  • Fin Pitch: 5mm (customizable for application needs)
  • Coatings (Optional): CED / Ozkem coatings for enhanced corrosion protection
  • Anti-Bacterial Treatment: Optional surface treatments for food-grade and pharmaceutical use
  • Defrost System: Integrated electric heaters or hot gas bypass for automatic defrosting
  • Testing: Each unit tested for leak integrity, airflow performance, and temp.erature consistency

Performance Data (Typical Range)

  • Temperature Range: -7°C (Evaporator Coil Temperature (Refrigerant Side) to +5°C (Defrost cycle behavior)
  • Cooling Capacity: depending on model and application
  • Defrost Cycle: Fully automatic with electric or hot gas options
  • Reliability: Built to ensure long service life under continuous operation
  • Hygiene: Optional coatings and anti-bacterial treatment for compliance with food and pharma standards
