Systems & Refrigerants
Which refrigerant is right for my plant — ammonia or Freon?
Ammonia (NH₃) is the efficient natural choice for large-scale industrial cooling, ice generation and cold storage. Freon (HFC) suits compact commercial and mid-scale systems. Our engineers recommend the right platform based on your capacity, temperature and site conditions.
What's the difference between your Ammonia and Freon ranges?
The Ammonia range covers evaporative condensers, plate ice machines, falling-film chillers, air cooling units and pressure vessels for large industrial duty. The Freon range covers air cooler units, condensing units, blast freezers, modular cold rooms and shell & tube for commercial and mid-scale work.
Is ammonia safe to use in a food facility?
Yes — ammonia is widely used in food and cold-chain plants worldwide. Systems are engineered with proper containment, ventilation, detection and safety devices, and commissioned to recognised safety standards.
Capacity & Specification
What capacity range can you design for?
From compact commercial units to multi-megawatt plant rooms. A single plate-ice line delivers up to 75,000 kg of ice per day, and our condensers scale to 700 TR in a single unit.
What temperature ranges do your systems achieve?
From +12 °C ripening rooms and +2 to +8 °C chillers down to −18 to −25 °C frozen storage, with blast freezing below −30 °C and specialised duties to −40 °C.
Can systems be custom-sized to my site?
Yes. Because manufacturing is in-house, units are engineered to your capacity, footprint and site conditions — including custom coil, fan and vessel configurations.
Project & Turnkey
Do you handle complete turnkey projects?
Yes. We design, manufacture, install and commission. That covers load calculation and system design, equipment manufacture in our own works, insulated panels and doors, piping and insulation, electricals and controls, refrigerant charging, performance testing and handover. Civil work, main incoming power and the building shell are normally outside our scope unless separately agreed.
What is included in your quotation, and what isn't?
Included: refrigeration equipment, panels and doors, plant room piping and insulation, control panels, installation and commissioning, and handover documentation. Typically excluded and quoted separately: civil work, main transformer and HT connection, DG set, water supply and treatment plant, material handling equipment, and any statutory fees. We list exclusions explicitly rather than leaving them to be discovered later.
Can you work with our existing building or existing plant?
Yes. A good proportion of our work is retrofit and expansion into existing structures. We survey the site first — floor loading, headroom, door positions, available power and existing pipe routes all shape what is possible. Retrofits often need staged commissioning to keep the running facility live, which we plan into the schedule.
Do you supply the complete cold room, or just the refrigeration?
Both. Modular cold rooms are built at site to your dimensions using PUF-insulated panels manufactured in our own facility, paired with refrigeration from our range. We also supply cold chain doors — sliding, hinged, automatic, high-speed and blast freezer — and undertake complete turnkey projects where we carry the single point of responsibility.
Quality & Manufacturing
What certifications do you hold?
We are ASME, IS 2825 and PESO certified. Pressure vessels — receivers, accumulators, separators and dish ends — are designed and fabricated to the applicable code with full documentation. Certification is not a badge on a brochure; it determines how vessels are designed, welded, tested and documented, and it is what your insurer and inspector will ask for.
IS 2825 or ASME — which should I specify?
IS 2825 is the Indian code and is accepted by statutory authorities across India, including for PESO purposes. ASME is generally specified for export projects, multinational clients, or where a corporate engineering standard requires it. We build to both. If your project has no external requirement, IS 2825 is normally the practical choice.
Is everything manufactured in-house?
Coil fabrication, sheet metal forming, pressure vessel fabrication, orbital welding and assembly are all done in our own works in New Delhi. Bought-out items — compressors, motors, valves, controls and instrumentation — are sourced from established manufacturers and stated by make in the offer, so you know exactly what you are buying.
How are pressure vessels tested before dispatch?
Vessels are hydrostatically tested to the pressure required by the applicable code, with dimensional inspection, weld examination and documentation of material test certificates. Test certificates and as-built drawings form part of the handover documentation. Where the project requires third-party inspection, we accommodate it in the manufacturing schedule.
Why does orbital welding matter on refrigerant-bearing joints?
Orbital welding produces a consistent, repeatable, high-purity weld with full penetration and minimal internal oxidation. On refrigerant joints that matters twice over: it reduces leak risk over a twenty-year life, and it keeps contamination out of a system where oil and refrigerant chemistry are sensitive to it. Manual welding is inconsistent by nature.
Can I visit the works before placing an order?
Yes, by appointment at our New Delhi facility. We would encourage it. Seeing coil fabrication, vessel welding and pressure testing tells you more about a supplier than any brochure, and it lets you meet the people who will actually build your equipment. Call ahead and we will arrange it around what is on the shop floor.
Service & Coverage
Where do you supply and install?
Across India and to export markets. Being specific about coverage is a competitive advantage — buyers outside the metros assume they will be neglected, and naming the regions you actually cover answers that.
