NESS Thermal oil heater (WEH / WEV)
High efficiency and balanced temperature profile
The two types of construction (WEH and WEV) do not differ in their mode of operation. In most cases, the local conditions and any existing facilities are the decisive factor for one of the two solutions.
Type WEV is usually suitable if there is little floor space available or if the fuel used does not burn residue-free, as cleaning openings can be provided on its bottom.
Type WEH makes the burner particularly easy to access for maintenance work. It is especially practical in combination with a combustion air pre-heater (Luvo), as it can be mounted directly on the heater. However, the use of a combustion air pre-heater is also possible in conjunction with a WEV.
