THE THERMAL CHALLENGE

What This System Was Designed To Solve

Seafood processing requires precise temperature management during continuous production. Thermal loads vary significantly depending on raw material intake, processing speed and ambient conditions.

BEFORE — BASIC COOLING APPROACH

  • Cooling equipment operating close to maximum capacity
  • Limited reserve during production surges
  • Reduced efficiency during tropical ambient conditions
  • Higher mechanical stress from frequent cycling

AFTER — ENGINEERED THERMAL NETWORK

-10°C
  • Additional capacity margin absorbs variable production loads
  • Dedicated cooling tower circuit maintains efficiency in tropical ambient
  • Closed-loop glycol distribution, no direct refrigerant in production areas
  • Buffer storage reduces fluctuation and improves compressor stability

Engineering Decisions

Why KWSL-080D Instead of Smaller Capacity?

Challenge

A system operating near maximum capacity has limited flexibility during production peaks.

Decision

Select higher-capacity low-temperature refrigeration equipment.

Benefit

Additional thermal reserve improves temperature stability and reduces equipment stress.

Why Water-Cooled Refrigeration?

Challenge

Thailand tropical temperatures increase condenser pressure on air-cooled systems.

Decision

Use water-cooled condenser with cooling tower heat rejection.

Benefit

More stable condensing conditions and improved efficiency.

Why Glycol Secondary Cooling?

Challenge

Production areas require flexible and safe cooling distribution.

Decision

Use closed-loop glycol circulation.

Benefit

Reliable low-temperature delivery without direct refrigerant circulation.

Why Thermal Buffering?

Challenge

Seafood production creates variable thermal loads.

Decision

Integrate glycol buffer storage.

Benefit

Stable temperatures and reduced compressor cycling.
