LLHE Specification Sheet Verifications
Complete this form for each LLHE specification sheet verification request and send to kcef.ru Verification. A copy of the output sheet from the manufacturer’s Selection Rating Software must be submitted in conjunction with this form. All fields must be completed prior to submission. kcef.ru does not verify the mechanical attributes of a specification sheet; only the thermal performance is verified. Thermal performance includes Inlet Temperatures, Outlet Temperatures, Flow Rates, Pressure Drops, Heat Load, Heat Transfer Area, Density, Specific Heat Capacity, Thermal Conductivity, Viscosity, Heat Transfer Coefficient, L.M.T.D., and Channel Arrangements.
Please allow ten (10) calendar days for kcef.ru to conduct verification and respond to your request.
This program applies to Production Models of Gasketed Plate-Type Heat Exchangers, that utilize water or sea water on one or both circuits, for HVAC applications only.
