We recently supplied Zululand Refrigeration three large Chilled water cooling coils for the retrofit of an existing direct expansion system. The existing plant room had a very old Trane Climate Changer DX air handling unit matched to large Trane 90 ton compressor. The client was convinced to convert the plant to chilled water – whereby a new Clint Chiller was purchased and Afcon supplied the new chilled water cooling coils to fit into the existing Trane AHU. Afcon also supplied a Foras water pump and Controlli three way modulating valve. The entire system is now controlled by a Carel electronics system, which as agents here in Natal we were able to specify and supply.
