We offer the the following services

New Installations & Maintenance

Chiller and freezer rooms for different applications. We are updated with the latest technology with digital controls, variable speed drives and monitoring systems. Installation teams work country wide on different projects, big or small. Our service department do maintenance on all kinds of chiller & freezer rooms, and specialised refrigeration equipment.

We carry most parts in our warehouse; service vehicles are fully equipped with general and specialised tools, and fast moving parts for prompt service. Well trained technicians are available 24/7/365 under hands-on supervision from management to ensure reliable repairs.

Only components of respectable brand names are used. Most parts are covered by a one year warranty and work is guaranteed with applicable terms and conditions.

Preventative Maintenance Programs

Routine services are done to maintain equipment on a regular base. These prevent breakdowns and stock losses.

Different maintenance programs / service agreements are available:

– Scheduled services monthly or quarterly services
– Pre and post-harvest services

Each service program is developed to accommodate the client’s unique needs. Quarterly & monthly programs available.

Monitoring Systems

 

 Monitoring, controlling and supervising web server.

This is a powerful monitoring engine which not only supervises cold rooms and/or display cabinets, but also manages some equipment in the building as lights, pumps, forklift chargers, etc.

The monitoring feature detects any irregularities and sends out alarms to prevent stock losses. E-mails can be sent to facility supervisor(s) and or maintenance contractor.

A full history is kept of all actions, settings and results; which can also be printed.

It further has a power saving feature in the CRO (Compressor Rack Optimizer) algorithm through plant optimization. If a controller is identified which needs more refrigeration power, it recalculate setpoints of other controllers to optimize efficiency to the identified system. It also controls plant efficiency to decrease energy consumption.

   Synthetic Refrigerants (HFC) & Natural refrigerants (CO2) / R744

Simplex, Miniplex and Multiplex Refrigeration for Commercial & Industrial applications

Simplex Refrigeration (100% energy consumption)
–  The most energy inefficient refrigeration plant available, but ideal in remote areas;
– Can be maintained by less skilled technicians.

Miniplex Refrigeration (up to 85% energy consumption)
–  Bring efficiency to small stores: convenient stores, small butcheries, etc.

Multiplex Refrigeration (up to 60% energy consumption)
The ultimate energy saver in supermarket, packhouse and industrial refrigeration.
– Bring even more huge differentials when applied with CO2 refrigerant with the advantage of a green refrigerant.
–  CO2 has superior power efficiency when compared to high tech HFC multiplex plants.
–  It has more capital cost but less running and maintenance cost.
–  Obtainable in subcritical and transcritical options.
