Plate Heat Exchanger — Dairy Milk Chiller & Heater
Dairy plate heat exchangers — chilling, heating and heat recovery — designed, supplied and integrated by ATMAN into your process line.
Get a PHE QuotePrecise Heat Transfer, Minimal Energy
The plate heat exchanger is the workhorse of every dairy — chilling incoming milk, heating for pasteurization, and recovering heat between the two to slash energy cost. ATMAN designs and integrates hygienic PHEs sized precisely to your duty.
Chill, heat and recover in one frame
Multi-section plate pack — regeneration, heating and cooling sections — delivers rapid chilling to 4°C, precise heating for pasteurization, and 90%+ heat recovery, all in a compact hygienic frame.
PHE Configurations
Milk Chiller (Cooling PHE)
Rapid chilling of raw or processed milk to 4°C at reception and post-process.
Milk Heater (Heating PHE)
Precise heating section for pasteurization and process duties.
Regenerative PHE
Regeneration section recovers heat between hot and cold streams — 90%+ efficiency.
Multi-Section Pasteurizer PHE
Combined regeneration, heating, holding and cooling for full HTST duty.
Why ATMAN PHEs
90%+ Heat Recovery
Regeneration cuts steam and chilling cost — the biggest energy lever in a dairy.
Rapid Chilling
Drops milk to 4°C fast, protecting quality and cold chain.
Compact & Hygienic
High surface area in a small footprint, food-grade and CIP-ready.
Precisely Sized
Thermal design matched to your exact duty, not an oversized catalog unit.
Global-Grade Components, Engineered Into One Line
Where the process demands it, ATMAN specifies and integrates critical components from world-leading brands (Alfa Laval, GEA, SPX / APV, Tetra Pak, IDMC), engineered into a single commissioned system, not sold as loose parts.

Frequently Asked Questions
What is a dairy plate heat exchanger used for?
Chilling incoming milk to 4C, heating for pasteurization, and recovering heat between the two streams to cut energy cost, all in one compact hygienic frame.
How much heat recovery does a PHE achieve?
ATMAN regenerative PHE designs typically achieve 90 percent or more heat recovery, sharply reducing steam and chilling running costs.
Can one PHE both heat and chill?
Yes. A multi-section plate pack combines regeneration, heating and cooling sections in a single frame for full HTST duty.
Do you size the PHE to our plant?
Yes. We do the thermal design to your exact heating and cooling duty and flow, not an oversized catalog unit.
