Industrial Water Chillers, Evaporative Condensers & Air Conditioners

ScaleAwayTM descaling products are an excellent choice for descaling water formed deposits from evaporative condensers, shell & tube condensers and centrifugal chillers.

ScaleAway Descalers will help rid your equipment of scale deposits and have them working in top efficiency in a matter of hours.

ScaleAway Antiscalers are liquid corrosion inhibitor programs designed for high heat flux systems.
These antiscalants are multicomponent inhibitors that provides metal corrosion protection and scale inhibition in closed loop cooling water systems.

ScaleAway Chiller Cleaning Service a chemical clean and power wash service your closed loop chillers.

ScaleAway Chemical Dosing System an effective preventative maintenence programme for your closed loop chillers - No more "hit-and-miss" hand dosing.

A good cleaning maintenance program undertaken by ScaleAway for industrial water cooling chillers and commercial air conditioning units, will increase operating efficiency, reduce energy costs, reduce downtime and provide more reliable performance of the chiller/cooling system.

A dirty chiller will adversely affect operations and require more power (increasing energy costs) to get the same cooling output as a clean chiller. A dirty chiller system also has to work harder, which puts excessive strain on the motors and the integral mechanical systems that include pumps and bearings. The end result, obviously, is a shorter operating life of the system.

Whenever there is a deposit of any type of heat transfer surface, it retards heat transfer. This is referred to as “Thermal Resistance” and requires a corresponding increase in energy to overcome it. Major manufacturers of air conditioning equipment generally design condensers and chiller heat exchangers to operate at maximum thermal resistance or fouling factor of 0.005. As a result, a deposit of only 1mm corresponds to an increase in energy cost of over 30%.

This 30% increase in cost relates to common calcium carbonate deposit. The actual heat transfer coefficient of a deposit depends what it is. Iron deposits of the same thickness are greater insulators and therefore have lower heat transfer coefficients. Certainly any deposit contributing to a fouling factor (thermal resistance) will increase electrical consumption and decrease efficiency.
The increase in electrical energy takes place in the compressor. Scale deposits will increase the thermal resistance causing higher refrigerant gas temperatures from the condenser. Higher refrigerant gas temperatures means higher gas pressures, which require greater energy to compress the refrigerant. Therefore, there is an increase in the electrical power required to operate the compressor.
Minimising this potential energy loss requires monitoring of the daily energy consumed per ton of refrigerant/air conditioning being generated. This will allow you to recognise when inefficient operation is increasing due to the deposit accumulation within your system. Fortunately ScaleAway descalers dissolve the toughest water formed mineral deposits from virtually any type of water based equipment or system.

Periodic descaling with ScaleAway descalers is necessary for maintaining your equipment at peak operating efficiency and maximum rated output!

Evaporative Condensers/Fluid Coolers
An evaporative condenser is designed to condense a refrigerant gas and a fluid cooler cools process water contained on the inside of the of the units condensing coil or tube bundle. The water is circulated from the basin or sump located at the bottom of the unit and distributed by spray nozzles to optimize coverage of the condensing coil or tube bundle. The spray nozzles will distribute water evenly over the condensing coil or tube bundle located in the mid section of the condenser/cooler. The fan at the top of the unit is used to pull air through the side louvers, enhancing evaporation, resulting in further cooling of the water during it’s descent back to the sump of the unit. Scale deposits form on the exterior tube surfaces of the heat exchanger coil, which acts as an insulating barrier. The ultimate result is inadequate cooling, over worked machinery and expensive inefficient operation. Scale can also form within the spray nozzles which will reduce coverage of the tube surfaces. A scaled evaporative condenser or liquid cooler cannot efficiently condense the refrigerant gas in the condensing coil or cool the water inside the tube bundle. Reduction in efficiency directly relates to added energy consumption and higher energy costs. This is where ScaleAway’s System Descaling CartTM comes into action! As the ScaleAwayTM descaling solution comes into contact with the scale deposits, they effectively dissolve them into solution, removing the insulating barrier and re-establishing the equipment efficiency. Ideally, a facility’s scheduled maintenance program would include chiller cleaning. The established method of determining the efficiency of the chiller is to monitor the operating pressures of the system. When pressures begin to increase, particularly head pressure, it’s an indication that chiller cleaning is necessary.

The removal of waterscale, limescale, sludge and rust from the waterside of your chiller with scale removers and dispersant is of paramount importance for the efficiency of your water chillers.

Ask yourself, can I afford not to do regular descaling, cleaning or chemical dosing?
