Industrial Refrigeration Solutions

DETAIL SERVICES

Ammonia and Freon systems for ice manufacturers, seafood and poultry processors, dairies, exporters and cold storage operators.

A refrigeration plant is a long term cost, not a one time purchase. Undersize the condenser and you pay for it every month on the electricity bill. Oversize the compressor and you pay for it up front and again in short cycling.

We have been designing and installing these systems in Sri Lanka since the early nineties. Our engineers calculate the heat load, select the refrigerant and equipment, install the plant and commission it at full load before handover. Our senior engineering staff includes USA qualified professionals.

Our Industrial Refrigeration Services

Refrigeration Plant Systems

We provide refrigeration plant systems designed to support industrial cooling, freezing, processing and cold-storage requirements.

Our team assists with system planning, capacity selection, equipment integration, installation and commissioning to help ensure stable operation and efficient temperature control.

Our Solutions Include

Chiller Plants

Ammonia and Freon chiller plants built to your process load. We design the plant, import the equipment, install it, and commission it at full load before handover. Ammonia suits large industrial duty and costs less to run. Freon suits smaller loads and sites where ammonia handling is not practical. We will tell you which one fits your operation rather than selling you the one with the better margin.

  • Import, supply, installation, commissioning and design of ammonia plants
  • Freon plants for medium and small industrial loads
  • Complete machine room layout, pipework, insulation and electrical
  • Controls and automation, including remote monitoring
  • Genuine spares for SABROE, FRICK, GRAM, YORK, MYCOM, GRASSO and BITZER

The condenser decides how hard your compressors work. In Sri Lankan ambient conditions, an undersized or fouled condenser raises head pressure and pushes power consumption up across the whole plant. We supply imported units and fabricate locally where lead time or budget matters.

  • Imported evaporative condensers sized for local ambient temperature and humidity
  • Local fabrication of condenser and receiver vessels
  • Replacement and upgrade of existing condensers on running plants
  • Water treatment and scale control advice
  • Cleaning and servicing under AMC

FRP type cooling towers for refrigeration condenser water and process cooling duty. Supplied, installed and connected to your existing pipework, with pumps and controls where needed.

  • FRP cooling towers, supply and installation
  • Sizing against condenser heat rejection load
  • Pump sets, pipework and basin controls
  • Servicing, fill replacement and cleaning

Screw and reciprocating compressor packages supplied complete with oil separators, controls and safety devices. We are an authorised Bitzer distributor and hold spares for the major industrial brands.

  • Screw compressor packages for continuous industrial duty
  • Reciprocating packages for smaller and variable loads
  • SABROE, MYCOM, FRICK, YORK, GRAM, GRASSO, BITZER
  • Compressor replacement and upgrade on existing plants
  • Overhaul, rebuild and genuine spare parts supply

Ice bank tanks store cooling capacity so your compressors run during off-peak hours and the load is there when production starts. That flattens your demand charge and lets you install smaller plant.

  • Imported ice bank systems
  • Local fabrication of ice bank tanks
  • Dairy, beverage and process cooling applications
  • Agitation, coil and control systems
  • Service and maintenance

Cooling & Freezing Systems

We provide cooling and freezing systems for facilities that require stable temperatures, product preservation and dependable cold-chain performance.

Each system is designed according to the product type, required temperature range, facility size, loading pattern and operating conditions.

Our Solutions Include

Cold Rooms

Cold rooms of any capacity, in PU panel construction. We build the room, install the refrigeration, fit the doors and racking, and commission it to your holding temperature. Panel thickness is chosen against your target temperature and ambient conditions, not against a standard spec sheet.

  • Supply, design, installation and commissioning of any type of cold room
  • PU panel construction, imported and locally sourced
  • Cold room doors, air curtains and strip curtains
  • Cold room racking systems, designed and installed
  • Dehumidifiers and FRP cooling towers where required
  • Service and annual maintenance

Blast freezers pull product temperature down fast enough to protect texture and shelf life. Hardening rooms hold it. Cold warehouses store it at volume. We build all three, sized to your batch weight and required pull-down time.

  • Blast freezer rooms, sized to batch load and pull-down time
  • Hardening rooms for post-blast product
  • Cold warehouses for bulk frozen storage
  • Freezer room panel, door and floor construction
  • Refrigeration plant, evaporators and controls

Chilled water generation and distribution for process loads. Where several production areas need cooling at different points, a central chilled water plant is usually cheaper to run and easier to service than separate DX systems on each.

  • Chilled water plant design and installation
  • Distribution pipework, pumps and insulation
  • Plate heat exchangers and buffer tanks
  • Process cooling for food, beverage and manufacturing
  • Controls, automation and monitoring

Food Processing & Freezing Systems

Food-processing facilities require precise and consistent cooling to protect product quality, maintain hygiene standards and support efficient production.

We provide engineered freezing and cooling systems for seafood, meat, poultry, vegetables, bakery products and other processed foods.

Our Solutions Include

IQF Tunnel Freezers

Straight-line tunnel freezing for exporters who need individually quick frozen product at grade. Belt speed, air velocity and evaporator temperature are set against your product and throughput.

  • Supply, installation, commissioning and design of tunnel freezers
  • Any capacity, sized to line throughput
  • Prawns, fish, vegetables, fruit and processed foods
  • Belt, drive and washdown systems
  • Service and annual maintenance

Spiral freezers give you long dwell time in a small footprint. Worth the extra capital cost when floor space is the constraint and throughput is high.

  • Supply, installation, commissioning and design of spiral freezers
  • Any capacity, including high-throughput export lines
  • Compact footprint for constrained plant layouts
  • Belt, drive, cleaning and defrost systems
  • Service and annual maintenance
