3 Split Sections
Minimizes Power, Water, and Space consumption. Features continuous ASTM A-249 Grade TP-304L coils, IP-56 TEFC motors, 2mm SS-304L sump tank, and 5HP KDS-314 pump.
Custom Heat Exchangers
Wide range of Shell and Tube heat exchangers engineered to specific thermodynamic client duties with easily demountable water heads for swift mechanical de-scaling.
ASME / IS Standard Rated
Heavy-duty pressure vessels precision fabricated in our Kolkata plant to ensure uninterrupted circulation and safety in high-capacity Ammonia and Freon circuits.
In marine seafood processing and coastal freezing installations, corrosive salt atmosphere and high cyclical pressures demand superior metallurgy. At KR Refrigeration, every component is manufactured to strict international quality codes.
Continuous winding with minimal welded joints eliminates leak hazards in high-pressure Ammonia loops.
Direct contact plates designed with internal refrigerant cavities for instantaneous enthalpy transfer.
Driven by TEFC squirrel-cage motors with IP-56 protection rated for hot, humid coastal climates.
Calculate the required refrigeration tonnage (TR) and recommended KR Refrigeration condenser or plate station setup according to your daily production volume.
Supplying freezing equipment and evaporative systems to leading marine exporters and cold chains across Kolkata, Odisha, Mumbai, Andaman, and coastal India.
Specialized in rapid contact plate freezers and heavy evaporative condensers.
Headquartered in Kolkata, KR Refrigeration is owned and operated by a dedicated industrial refrigeration engineering team. Our years of research and hands-on site experience deliver tailored rapid low-temperature freezers that enhance product quality, grade value, and yield with minimum power consumption.
Our specialized extruded aluminium alloy freezing plates ensure maximum product contact allowing uniform freezing across ammonia, freon, and sub-critical CO₂ circuits. Combined with our split-section modular evaporative condensers (50 – 400 TR) and ASTM A-249 Grade TP-304L coils, we provide turnkey freezing security to India's top seafood exporters and cold warehouses.
Lower electrical consumption per frozen ton.
Condensers split into 3 sections for swift erection.
