GEA Grasso Service Equipment

Southern Sales & Services offer the GEA Grasso dryer which is a useful supplement for every ammonia refrigeration plant. It eliminates infiltrated water from the refrigerant circuit, even while the plant is in operation. Water has a huge affinity with ammonia and the combination effects the evaporation temperature and finally the efficiency of the plant.

Southern Sales & Services also off the GEA Purger which increases the efficiency and improves the characteristics of every industrial refrigeration plant

GEA Ammonia Dryer

The GEA Grasso Ammonia Dryer is a perfect supplement to your ammonia refrigeration system to ensure longer operational life as well as lower operating and maintenance costs.

The ammonia dryer removes water from the refrigerant cycles without having the machines shut down. It keeps the refrigerant circuit dry and clean and your refrigeration system running efficiently.

Even low water quantities can influence the evaporation temperature by up to 1K, which results in an increased power consumption of around 3%.

In addition to increasing the operating costs, the water causes corrosion, leads to rapid ageing of the oil and quickens the forming of slurry. For these reasons the infiltrated water results in higher maintenance costs. If the refrigerant circuit is dry and clean these drawbacks can be prevented.

Customer benefits:

• Simple installation in any existing or newly erected application
• Longer lifetime of each system component
• Prevents energy wastage
• Short pay back period
• Premium quality and simply to operate
• Built in accordance to CE PED rules

GEA Self-Limiting Automatic Purger

Non-condensable gases cause considerable loss of efficiency. Air or other non-condensable gases can dissolve in the refrigerant and come into circulation in the refrigeration system, causing even in small concentrations a significant increase in condensing pressure due to their different/higher partial pressures. Refrigeration systems must therefore be kept as free as possible from non-condensables.

The most effective way of doing this is by automatic purging, as this responds immediately to any entering of non-condensables in the system. The Self-limiting Automatic Purger is a purging device which reduces the concentration of non-condensables to a negligible percentage, with a just as negligible loss of refrigerant.

This patented self-limiting Automatic Purger starts only when the concentration of non-condensables in the liquid receiver is 2% or more and stops when this concentration has dropped to below 1%. Since, in the entire installation, the average concentration of non-condensable gases is much lower, this represents an average concentration in the installation of less than 0.1%
