zehnder nova
Product description
zehnder nova Description Zehnder Nova is a radiator composed of flat tubes that form a solid, steel heating surface. In horizontal models, the flat, water-conducting tubes are aligned horizontally and in vertical models – vertically. Additionally, the flat tubes may be equipped with convection fins. The flat tubes of 70 x 8 mm oval cross-section are welded under pressure to symmetrical manifolds with a 1 mm air gap; the weld seams are practically imperceptible. The radiators are primed, coated with powder enamel of desired colour, and are baked following the requirements of DIN 55900. The heat capacity is tested in accordance with DIN EN 442 standard. The radiator complies with the requirements of the GUV (German Accident Insurance). Single-row and double-row models, models with decorative covers and with fins. Same side connection (left or right): for horizontal models – 2 x 1/2“ (female thread), for vertical – 4 x 1/2“ (female thread), air vent 1/2“. Suspension brackets are welded to the radiator’s back surface. The radiator is supplied in an installation-ready package; by request: • a desired mounting set • other connection codes • other colour choice from 700-colour palette of RAL and NCS S • special shapes • high-pressure design max. 10 bar (13 bar test) • decorative grille for horizontal models The picture shows the vertical model Advantages • wide range of models • low water volume • short heat-up time • horizontal and vertical designs • low installation depth • modern, elegant design Standard equipment • radiator, primed and finished with powder enamel of RAL 9016 colour • side connection (female thread) 1/2“ • air vent • welded-on suspension brackets

Attention: For Zehnder Nova radiators connected in series, the minimum water flow rate must comply with the following table: Zehnder Nova radiators may be connected in series, as shown on the drawings above. The radiators are shipped separately, connections shall be performed during installation. No more than three 6000 mm long Zehnder Nova radiators may be connected in series. The recommended connecting element size is 3/4“. Zehnder Nova radiators must be connected in accordance with the shown arrangement. When placing an order, please indicate the number of the desired installation arrangement. For an additional cost (per request).

For two-row Zehnder Nova models, the serial linking arrangement and the manner of connecting are as follows: flow – at the radiator’s front panel, return – facing the wall.
Pressure losses
zehnder nova Determining pressure loss ΔP Pressure losses for the Zehnder Nova radiator are calculated by using the following equation:
The pressure loss constant, being a function of the mounting type and height and the connection code, is taken from the following table. Example: model NH 70, installation length 1000 mm,
ΔP = qms1,9125 • C
same-side connection, qm = 62.0 kg/hr
ΔP = pressure loss in Pa qm = water flow rate in kg/hr
pressure loss constant C = 0,2993
C = pressure loss constant
Result:
ΔP = 62,00 1,9125 • 0,2993 ΔP = 802 Pa
