DC ProMech Services Ltd had frost coils specially made to fit into the existing space. We attended site and removed the existing frost coils and pipework. We fitted new frost coils, replaced the badly corroded pipework, repainted and insulated the pipework. We added new weatherproofing to the insulated pipework, tested the new frost coils and confirmed they met the original specification for the required temperature drop across the coil and fluid temperature drop through the coil. We adjusted the commissioning valves to ensure the system worked in accordance with design specification.
