Air Cooled Industrial Water Chillers & Chilling Plants Supplier manufacturer in Dubai UAE SAUDI ARABIA KUWAIT BAHRAIN OMAN

DANA WATER HEATERS & COOLERS FACTORY LLC ( An ISO 9001:2015 Certified Company) is One of the largest and oldest (Est. 2001) manufacturer of Air cooled Water Chillers & Chilling Plants for Domestic and Industrial Usage.

Where aesthetics and environmental conditions or water access restrictions exist, air-cooled chiller may be applied. Both air-cooled and water-cooled chillers depend on an air stream as a means of heat transfer.

The difference is that the water-cooled chillers or rather the cooling towers use a humid air stream (ambient air stream + water spray) while the air-cooled chillers use a current of ambient air.

Normally water-cooled chillers are cheaper and more efficient, with the disadvantage of high water consumption.

Unfortunately, some people still believe that air cooled chillers cannot offer quite good efficiencies. What such people only need to check is the performance of these chillers two decades ago is the progressive increase in NPLV rating of air-cooled chillers over the years.

Already, many chiller plants in the Middle East and elsewhere have adopted DANA’s air-cooled designs and have expressed satisfaction. When used in part load applications, these chillers are very reliable.

Salient Features of Air Cooled Water Chillers :-

  • No cooling towers required
  • Better environmental stability-no water wastage
  • Low maintenance costs
  • Easier to operate and control-tower freezing and tower bypass absent
  • Chemical costs avoided
  • Water costs avoided, especially in cities
  • No water problems to deal with in case of disaster

SUB-COMPONENTS OF DANA AIR COOLED WATER CHILLERS/CHILLING PLANTS :-

  1. COMPRESSOR – At DANA we are focussing on Quality and We are Proud to use EMERSON COPELAND compressors in All our Units.These Specially designed compressors are selected based on the application and are are also specially ordered to withstand the harsh Gulf Climatic conditions.

Models: CR,ZR,ZB Etc

  • Copeland Hermetic, Scroll axial and radial compliance for superior reliability and efficiency.
  • Gas – R22, R410A, R407C, R134A
  • Low TEWI (Total Equivalent Warming Impact)
  • Low sound and vibration level
  • Low oil circulation rate
  • Copeland qualified tandem and trio configurations for superior seasonal efficiency (ESEER)

2. WATER PUMPS :- We are using PEDROLLO branded Italian Pumps for our Water Chillers. On Client Request we are also using pumps by GRUNDFOS

The high efficiency and adaptability of these pumps to even the most unusual of applications, makes them ideal for use in the domestic, civil and industrial sectors; in particular for the distribution of water in combination with pressure sets, for pressure boosting and in fire-fighting sets. Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
The pump should be installed in an enclosed environment, or at least sheltered from inclement weather.

Ranges:  0.5HP to 3 HP

Application Limit:

  • Temperature of the liquid from -10 °C to +90 °C
  • Ambient Temperature from -10 °C to +40 °C

3. CONDENSER COILS :-  All our DANA Condenser Coils are made on OEM for our special requirements as per our HVAC design.

Round seamless copper tubes are mechanically expanded into the fin collars of the secondary surface. The mechanical expansion provides a permanent metal-to-metal bond for efficient heat transfer. Tubes are staggered in the direction of airflow.
  • OEM and Replacement Coils for Every Application
  • Cross Reference All Major Brands
  • Quick Response
  • Field Measurement Available
  • Heresite coated.
