Chemical Foam Cleaning
Using our state of the art, newly patented foaming system, National Heat Exchange can restore cooling efficiency and reduce downtime. This system is designed to chemically remove accumulations or organic and inorganic deposits such as oils, calcium, dust, dirt, and other deposits that inhibit heat transfer. We apply a heavy "shaving cream like" foam into and around the cooler coils. As the foam dissipates, the deposits are gently removed from the cooling surfaces. This unique cleaning method minimizes chemical requirements by keeping the chemical in place on the deposit long enough for the active ingredients to penetrate and remove the deposits from the coils.
