DSV Air & Sea has taken into use a new facility at Schiphol Rozenburg. Geerlofs Refrigeration designed and built the refrigeration system of the new facility at Incheon Road near Schiphol. Also Geerlofs supplied the insulated panels and doors. The facility is split into two parts to separate the pharmaceutical business from the other perishables.
The core of the industrial refrigeration system is a indirect ammonia compressor unit of over 600kW. Making use of a natural refrigerant means not only elevated energy efficiency, it as well ensures compliance with newest legislation regarding industrial refrigeration. These new rules demand the use of refrigerants which don’t contribute in a negative way to the greenhouse effect: ammonia has the best specifications possible and has zero impact on CO2 exhaust when released.
Frequency control is applied to increase energy efficiency further and enables demand driven capacity control. Heat recovery is used to create energy neutral defrosting of evaporators and delivers the necessary heating power for ambient temperature areas. Of course, adequate redundancy is in place and sensitivity to malfunctions is therefore reduced.
The facility has three temperature zones at the pharmaceutical side: ambient, cooled and frozen. This part of the building has been temperature mapped at commissioning to ensure suitable temperature control.
The perishable side has several temperature zones as well to create suitable climates for food and flower produces. A vacuum cooler is part of the system to cool down certain perishables like flowers and leafy vegetables, amazingly quickly. The vacuum cooler does require complicated technology to enable instant delivery of high cooling capacity at the so called flash point of the vacuuming process. Gismo, Geerlofs’ remote monitoring service, is part of the contract.
