Re; maggot room evaporator

Hi all , and a big premature thanks to all who can help, a new customer ive aquired has been miss sold an evap for useage on cooling maggots . I rang an old number for ss coils ,but the chap there said they no longer did these, he did however give me the number for thermofrost cryo who ive rang twice and have not rang me back, i contacted beehive coils and they can electro plate an evap ,but im after the full blower/heaters inc .Does any body have a contact number for a british manufacturer ? im based in the south yorkshire area , thanks Ian
