Evaporative Condensers for ammonia plants in food processing factories
Ammonia systems are the most efficient systems available for industrial-scale refrigeration facilities and allow the condensation process to be carried out at a temperature closest to the wet bulb temperature. Any modification of the condensing process increases or decreases the facility's efficiency coefficient by about 3%. Evaporative condensers can reduce the condensation temperature by 5-7 degrees centigrade, which means an energy saving of approx. 15-20%.
Evaporative condenser manufactured by the international company EVAPCO, which Krashin-Shalev represents in Israel since 1998.
The objective
The Design of an evaporative condenser for an ammonia cooling facility that meets the following requirements: Compliance with pressure vessel standards - such as: The European Standard PED, compliance with required performance, ease of maintenance and servicing, anticorrosive protection.
The challenge
Ammonia is a dangerous and malodorous substance and mistreatment of it can cause a calamity up to the point of fatalities. The most stringent standard requirements pose to manufacturers of any single component of the Ammonia System a considerable demanding challenge.
The Project’s Solution
In order to meet the above stringent requirements, a solution was proposed as follows: We chose an evaporator condenser from the international company EVAPCO, which Krashin-Shalev represents in Israel since 1998, with a very large built-in heat exchanger and with extremely small fan motors. Engines installed at the bottom of the unit have very convenient access for maintenance. Evaporative Condensers performance have been tested and measured at EVAPCO, Laboratories, which is the European standard for pressure vessels, including the handling of toxic substances such as ammonia. Anticorrosive protection - 725 grams of zinc per square meter - the thickest protective layer in the industry.
The outcome
We supply evaporative condensers for ammonia condensation in Israel since 2001. We have been meeting successfully stringent energy-saving requirements and zero safety faults, and we are confident that those systems will continue to do so. Since 2001 and until now, no replacement of these equipment models were required in Israel.
