Doors for Cold Storage, Food & Pharma Warehousing
India's cold chain loses energy — and product — at the door. Every open second dumps conditioned air; every iced-up gasket degrades the seal a little more. Egis Enterprises builds cold-room doors for each temperature band: chiller (0 to +15 C), freezer (to -28 C), blast freezer (to -40 C) and gastight controlled-atmosphere chambers, plus fast-cycle freezer doors for pallet-traffic openings.
The engineering is band-matched: 80 mm leaves for chillers, 120 mm with heated frames for freezers, 170 mm with heated multi-point gaskets for blast duty, and inflatable gaskets with pressure-decay verification for CA chambers. Fast automatic operation minimises the open-time window that dominates energy loss, and food-safe finishes with stainless options meet hygiene expectations.
The challenges
Energy loss
Air exchange through open or leaky doors dominates cold-store energy cost — more than conduction through the closed leaf.
Ice at the seal
Frost on gasket lines prevents sealing, admits more moisture, and cascades into permanent ice-up.
Thermal shock
Blast cycles swing temperatures violently; thin leaves distort and open gaps.
Atmosphere loss
CA chambers leak money through unmeasurable door leakage — nitrogen generators compensating for unknown gaps.

Egis surveys the facility — temperature bands, traffic patterns, existing openings — and specifies the door set band by band, then installs and commissions it as one system with one service schedule across the whole cold store.
Doors for Cold Storage, Food & Pharma Warehousing — FAQs
By the room's operating temperature: 0 to +15 C → ChillGlide C80; 0 to -28 C → FrostGlide F120; to -40 C → BlastShield B170. Using a chiller door in a freezer room is the most common cause of premature cold-store door failure.
Most loss is air exchange while open. Cutting open time from ~20 seconds to ~4 seconds with a fast automatic door reduces that exchange proportionally. Egis models the saving for specific openings during survey.
