MARINE AND INDUSTRIAL REFRIGERATION REFRIGERATED CARGO HOLDS Gill-finned tube air coolers for The air coolers are designed for mounting below the deckhead and operates by means of gravity (natural) air circulation. ♦ Even temperature throughout the hold ♦ No electric installation required ♦ No moving parts (fans, etc.) ♦ Less de-hydration of un-wrapped or un-boxed product ♦ Reduced energy consumption ♦ Better working environment ♦ Suitable for halocarbon, ammonia or brine systems ♦ Simple-, quick and low installation cost Manufactured from steel tubes fitted with spiral wound corrugated steel finned gills. The tubes are supported by tube plates, the number depending on cooler length. Refrigerant connections by means of welded-, threaded- or flanged ends. The entire cooler is hot-dip galvanized after assembly and pressure testing, ensuring a high degree of corrosion protection, optimum heat transfer and hygiene. Defrosting is done by means of hot-gas, hot brine or manual brushing, depending on the installation HALDEN - OSLO

REFRIGERATED CARGO HOLDS Standard coils for natural air circulation with the following dimensions: Total length of the coil Gilled length of the coil Center distance between the supporting plate LQ is 1200 mm on all coils, except coil with LB = 1750 mm, where Lc = 900 mm. This gives the follwing number of supporting plates for the different coil-lengths: The height of the coil is appr. 103 mm. In the following table there are given some data for the coils.
