01
Control
Our valves open and close the flow of ammonia automatically, so the plant keeps the right temperature on its own.
Industrial refrigeration controls · Made in India since 1978
Keeping the cold chain safe, since 1978.
We make the valves, controls and safety systems that keep ammonia refrigeration plants running. Think of the cold rooms behind your milk, your medicine and your ice cream. Our parts make sure the cold never stops, and nobody gets hurt.

New to refrigeration? Start here
Big cold rooms run on ammonia. Ammonia needs careful hands.
Dairies, breweries, drug makers and cold stores use ammonia to make cold, because it is efficient and kind to the climate. But ammonia is under high pressure, and it is dangerous if it leaks. Every pipe needs a valve that opens and closes at the right moment. Every tank needs a control that keeps the level right. Every plant needs alarms that speak up before a small problem becomes a big one. That is our work.
02
Protect
Our safety valves, leak detectors and alarms protect your people, your stock and your building.
03
Save
Our purgers and dehydrators clean air and water out of the system, so compressors work less and power bills drop.
04
Watch
Our data loggers send temperatures and pressures to your phone, so you can see your plant from anywhere.

Industries served
Built for the plants that keep food, drinks and medicine cold
Not sure which products suit your plant? Pick your industry. Each one has its own pressures, and we have been solving them for decades.
Dairy
From milk chilling to the cold store, approved by India's National Dairy Development Board.
Milk spoils fast if chilling slips. Steady levels and clean defrost keep every batch safe.
Beverage & Breweries
Steady temperatures for brewing, fermentation and bottled storage.
A brew that runs warm loses its taste. Precise valves hold each tank on target.
Pharmaceutical
Precise, monitored cooling for medicines that must never get warm.
Medicines lose strength when they get warm. Monitoring proves the cold held, every hour.
Bulk Drugs, Dyes & Intermediates
Safe, stable process cooling for chemical reactions.
Many reactions give off heat. Reliable cooling keeps them under control.
Chemical
Dependable controls for heavy process refrigeration.
Process plants run day and night. Parts must work for years without fuss.
Food Processing
Cold chain control from the processing line to the freezer.
Frozen food must stay frozen from line to truck. Defrost and level control make that easy.
Cold Storage
Keep every pallet at the right temperature, every single day.
One warm night can cost a full store of stock. Alarms and live data warn you early.
Ice Cream
Deep-freeze control, watched live from your phone.
Ice cream that thaws and refreezes is ruined. Deep-freeze control keeps it perfect.
Staple Fibre, Nylon & Textile
Process cooling for fibre and textile production.
Fibre quality depends on steady temperatures. Our controls keep the process even.

Why plants choose Manik Engineers
Trust in this industry is earned slowly. Here is how we have earned it.
In 1978, most refrigeration controls used in India were imported. They were costly, and spares took months to arrive. Mr. Shekhar Kulkarni, an IIT Bombay alumnus, started Manik Engineers in Pune to change that. Almost five decades later, the same idea drives us: build controls good enough for the world's biggest plant builders, make them here, and stand behind every one.
1978
48 years of one craft
Founded in Pune by Mr. Shekhar Kulkarni, an IIT Bombay alumnus. His goal was simple: make world-class refrigeration controls in India, at an honest price, so Indian plants did not have to import them.
CE / PED
Certified for Europe
Our pressure equipment is certified to the European Pressure Equipment Directive 2014/68/EU. We are the only Indian refrigeration controls company with this certification.
OEMs
Chosen by the builders
The companies that build refrigeration plants, including Johnson Controls, York, Kirloskar Pneumatics, Alfa Laval, Frick, Sabroe and Mycom, have standardised our controls for decades.

One maker, the full range
Valves, level controls, safety systems, energy savers and IoT monitoring. 89 products in 11 categories means one supplier, one quality standard and one phone number.
4 checks
Before anything ships
Raw material is inspected by hand before production. Finished products are is tested for design, performance, dimensions and corrosion resistance before it leaves our factory.
Global
Ready to export
We supply plants across the Middle East, Asia Pacific, Africa and Australia, with dealers in the Philippines and Russia.
How every product is checked
Step 1
Material check
Raw material is inspected by hand before any work begins.
Step 2
Design check
Each finished product is checked against its design, so it works as drawn.
Step 3
Performance test
Valves and controls are tested in our own testing facility before they leave.
Step 4
Size and corrosion check
Dimensions are measured, and resistance to corrosion is checked.
Your plant, with and without the right controls
| The problem | Without | With Manik |
|---|---|---|
| Air trapped in the system | Compressors push harder and power bills climb. | An automatic air purger removes it, day and night. |
| Water and oil in the ammonia | Parts wear out and cooling gets weaker. | The WDO separates them out, using heat the plant already has. |
| Ice on the cooling coils | Rooms warm up and coils work badly. | Hot gas defrost clears the ice without stopping the plant. |
| An ammonia leak | People are at risk and you may not know until too late. | Leak detection and alarms speak up at once. |
| Nobody at the plant at night | You find out about a problem in the morning. | The data logger shows live readings on your phone, anywhere. |
| Salty, humid or outdoor air | Ordinary valves rust and start to leak. | Stainless steel valves are built for it, up to 150 bar. |

Our most requested valves, purgers and monitoring systems. Each one solves a problem plant engineers face every day.
01 — IoT Data Logger
Watch your plant from anywhere
Records freezer and cold room temperatures, plus compressor suction, discharge, oil and intermediate pressures. All live, on your phone, tablet or computer.
Why it matters: you see a problem on your phone before your stock is lost.
- 16 inputs (upgraded from 8)
- Temperature and pressure
- Running in plants for 10+ years
02 — MS9B
Gas-powered solenoid valve
A strong, heavy-duty valve that opens and closes refrigerant flow on an electric signal. Because gas pressure does the work, it stays reliable in deep cold and thick oil.
Why it matters: defrost works properly, so coils stay clear and the room stays cold.
- Ammonia, R22, R134a, CO2
- Suction and defrost lines
- Works at low temperatures
03 — MCK2
Gas-powered suction stop valve
Closes suction lines firmly during defrost. Its spool-type piston resists dirt better than common designs, and the ductile iron body is tougher than grey iron.
Why it matters: dirt in old plants jams weaker valves. This one keeps closing tight.
- Ductile iron body
- Manual opening stem for servicing
- Pilot line strainers included
04 — MHPSV-SS
High-pressure stainless stop valve
Shuts off sections of high-pressure lines. Stainless steel stands up to humid, salty, coastal and outdoor air. The seal can be replaced while the valve is still working.
Why it matters: coastal and outdoor plants stop losing valves to rust.
- Up to 80 bar g (1160 psi g)
- -60°C to +150°C
- CF8 cast stainless body, PTFE seat
05 — MSGP-2E
Automatic air purger
Air trapped in a refrigeration plant makes compressors work harder. This unit finds it and removes it, automatically, so your condensing temperature stays where it should.
Why it matters: less air means lower power bills and less wear on compressors.
- Fully factory assembled
- Installs at ground level
- Can serve many purge points
06 — WDO
Ammonia purifier / dehydrator
Water and oil in ammonia slowly damage a plant. The WDO separates them out continuously, using heat the plant already has, so it costs almost nothing to run.
Why it matters: a clean system runs cooler, uses less power and lasts longer.
- Energy-neutral operation
- Self-regulating, low maintenance
- Short payback time
