What is controlled atmosphere storage?

Controlled atmosphere (CA) storage is a cold storage method that regulates oxygen, carbon dioxide and humidity levels inside a sealed store, alongside temperature, to slow the ripening and respiration of fruits and vegetables. This extends shelf life far beyond standard refrigeration alone, making it the preferred storage format for agri-export businesses handling apples, pears and other long-storage produce.

Ammonia vs freon refrigeration — which is better?

Ammonia refrigeration plants are generally more energy-efficient and better suited to large-capacity industrial cold storage, but require stricter safety handling due to toxicity. Freon (HFC/HCFC) refrigeration systems are easier to maintain and commonly used in smaller cold rooms and retail cold storage. The right choice depends on capacity, budget and safety infrastructure.

How does an IQF system work?

An IQF (Individual Quick Freeze) machine rapidly freezes individual food items — such as seafood, fruit pieces or vegetables — using high-velocity cold air or cryogenic methods, so each piece freezes separately rather than clumping together. This locks in texture, nutrition and appearance, which is why IQF machine technology is the standard for export-quality frozen food production.

How can I reduce cold storage energy consumption?

Cold storage energy consumption can be reduced through high-efficiency compressors, properly sized PUF panel insulation, smart temperature controls, regular preventive maintenance and AMC services, and minimising door-opening losses with dock shelters and dock levelers. Singhania Refrigeration's energy-efficient refrigeration systems are engineered to cut running costs by up to 30% compared with conventional installations.

Doors & CA Doors Manufacturer in India

Insulated Cold Room & Controlled Atmosphere Doors Built for an Airtight Seal

At Singhania Refrigeration, we design and build insulated Doors & CA Doors for chiller rooms, freezers, and controlled-atmosphere (CA) stores — access points that must keep their seal through hundreds of openings a day, not just look insulated on a spec sheet.

Our doors are engineered for Indian cold chain and CA storage conditions. With precision sealing, heated frames for sub-zero applications and food-safe hardware, the room behind the door stays exactly as controlled as it's supposed to be.

What is a Cold Room Door or CA Door?

A cold room door is part of cold storage infrastructure solutions, built as a specially insulated door that seals a chiller, freezer, or cold storage room from outside air. Unlike a standard door, it needs to maintain its seal in the face of a constant temperature differential, and repeated opening and closing.

A CA (controlled atmosphere) door takes it a step further. CA rooms do more than just control temperature; they control the gas atmosphere inside, usually by reducing oxygen and controlling carbon dioxide levels, which extends the storage life of produce such as apples. Even a small air leak at the door can ruin days of careful atmosphere control, so CA doors are made to a near-hermetic seal standard, much higher than is needed for a standard cold room door.

Doors & CA doors are used for access points which keep their seal in cold rooms, freezers and CA stores like cold storage warehouses, blast freezers, CA fruit stores, food processing plants and pharmaceutical cold rooms.

Key Features of Our Doors & CA Doors

Precision sealing system for cold room door

Precision Sealing Systems

The door frame is fitted with engineered gaskets and latch pressure to reduce frost formation and air leakage.

Heated frame and threshold for freezer door

Heated Frames & Thresholds

In freezer and sub-zero applications, built-in heating prevents ice buildup around the seal so the door continues to close properly over time.

Sliding & Hinged Variants

Choose the door type that matches your traffic pattern and room layout, from chiller to freezer to CA room.

Food-safe easy-clean cold room door finish

Food-Safe, Easy-Clean Finishes

Hygienic, smooth surfaces and food-safety-standard hardware throughout.

CA-Grade Sealing Where It Is Needed

Doors for controlled atmosphere rooms are built to the near-hermetic standard that gas-controlled storage really needs.

Heated-Frame Expertise for Sub-Zero Doors

Designing freezer and blast-freeze doors involves not just insulation value but also frost prevention at the seal.

Built to Your Actual Opening

Custom sizing means the door fits your room, not your room fits a standard door.

Pan-India Installation & AMC Support

Service coverage for warehouses, processing plants, and CA stores all over India.

Frequently Asked Questions

A standard cold room door is primarily designed to contain temperature and is sealed sufficiently to reduce heat loss and frost. CA (controlled atmosphere) rooms control oxygen and carbon dioxide levels, not just temperature, and CA doors are built to a much tighter, near-hermetic seal, because even a small leak can undo the atmosphere control that is keeping the stored produce fresh.

Every time you open the door in below-freezing temperatures, the moisture in the air condenses and freezes around the door seal. The heated frame and threshold stop that ice buildup, so the door continues to seal properly instead of slowly failing to close flush.

That depends on traffic. Hinged doors are ideal for small rooms with a lot of foot traffic and not many openings. Sliding doors generally lose less cold air when opened and are better at handling forklift traffic and high cycle counts, which is a bigger concern in busy warehouses.

Yes. Doors are cut to the actual opening of your room, not a standard size, and can include safety hardware and view apertures as required.

Vision panels let people outside see whether someone is inside before closing the door, and panic release hardware lets staff exit from the inside even if the door is latched.

Yes. We're based in Delhi NCR, but we provide installation and AMC support all over India for cold storage warehouses, CA stores, and processing plants installing or servicing these doors.
