In contrast, many contemporary refrigeration systems utilise element heaters for evaporator moisture removal. These heaters, resembling straightened electric jug elements, reach high temperatures towards the end of the defrost cycle, leading to various issues such as heater element failure, damaged evaporator tubes potentially causing refrigerant leakage, electrical cable and joint failures as well as issues with contactors, overloads, controls and safety components.
Furthermore, electric elements emit substantial heat into the freezer room, necessitating additional cooling upon refrigeration plant restart. This excess heat carries moisture from the evaporator into the freezer room, where it condenses and refreezes on surfaces including ceilings, walls and stored products.
In contrast, warm glycol defrosting dispenses with the electrical system, substituting it with glycol heated by waste heat from the refrigeration plant. During defrost cycles, a pump transfers warm glycol from a storage tank to the evaporators, where its gentle heat effectively melts ice, allowing it to drain without raising temperatures to levels that could reintroduce moisture into the freezer room.
This method ensures a dry, frost-free freezer environment and significantly reduces the cooling load following a defrost cycle, proving to be one, if not the most efficient method.
Strathbrook Refrigeration Servies boasts significant experience in managing commercial and industrial projects.
Strathbrook Refrigeration Servies specialises in designing and installing bespoke ammonia cooling and blast freezing systems for industrial and commercial settings, leveraging ammonias effectiveness in extreme temperature conditions.
Carbon Dioxide (CO2) serves as a long-term, naturally occuring replacement for many currently available GFC- type refrigerants, known for its exceptional energy efficiency and non-toxic nature. Its rapid expansion across various applications is driven by reduced power consumption and smaller, quieter plant rooms, making it a cost-effective and versatile option for refrigeration needs.
To prevent any unexpected breakdown or malfunctions, regular servicing of refrigeration plants/equipment and air conditioning is required.
We recognize that refrigeration and air conditioning issues can arise at any time and your refrigeration plant runs 24/7, which is why we provide round the clock emergency breakdown service.
