Dividing wall ATP specifications

  K factor coefficient Minimum thickness of dividing wall
Removable Fixed
GRP floor Longitudinal 2.0 W/m². K 1.5 W/m². K 25 mm
GRP floor Transversal 2.6 W/m². K 1.5 W/m². K 40 mm
Aluminium floor Longitudinal 3.0 W/m². K 2.0 W/m². K 25 mm
Aluminium floor Transversal 3.2 W/m². K 2.0 W/m². K 40 mm

Dividing wall coefficients include a safety margin to allow for degradation and thermal leakages.

Return air Bulkhead

Important Return air bulkhead panel to be of solid fixed type allowing a minimum return air gap of 52 mm from the evaporator panels and the top should be closed to conform to Thermo King recommended minimum standards.

Recommended minimal distances

A Minimum 52 mm B Minimum 82 mm
C Minimum 200 mm D Minimum 1927 mm

Thermo King recommended return air bulkhead specification

Note Dimension B MUST be maintained, no matter what the thickness of the trailer wall. With thicker trailer wall where the refrigerated unit is not protruding into the box; maintaining dimension A could reduce dimension B to less than 82 mm. If this is the case, dimension B must be maintained to 82 mm and as a result of this, dimension A may be more than 52 mm.
