CX3000 – Accessories HW – Water heating coil (internal) The water heating coil (internal) is a space-saving addition to the CX3000 ventilation unit. It enables effective temperature control of the supply air and is also used for power compensation during the defrosting process of the heat exchanger. The installation of the heating coil is extremely easy and time-sa- ving, as the mounting brackets and duct connections to the outside are already prepared in the ventilation unit. HW - Water heating coil In addition, the required 3-way control valve for heating capacity control can be calculated using the user-friendly online product selection program EXselectPro. This handy tool makes selecting and configuring the control valve a hassle-free process. B C A Technical specifications Item no. Unit size Test pres- sure [kPa] Max. opr.

It is supplied in an insulated enclosure (50 mm) and offers versatile installation options. The connection can be made either directly to the CX3000 air handling unit or in the outdoor air duct. The preheating coil plays an important role in B providing extra protection for the counterflow heat exchanger, especially at extremely cold outdoor temperatures below -16°C.
