-3-Section 1Introduction

SUNSRAYS "D"series Air Heating Burners and "D"series Duct Burner systems are designed to provide a high efficiency,high turndown,low emission solution for air replacement or “make-up”air heating applications.

They are ideally suited to offer precise temperature control for applications such as:•Paint spray booth air heating -spray and bake cycles •Parts dryers •HVAC air replacement schemes for factories,warehouses,distribution centres …•Crop dryers

SUNSRAYS "D"series burner assemblies can either be supplied as:

A.Individual units for integration into “customer”designed air heating modules.

or within

B."D"series Duct Burner systems which also incorporate a duct mounting plate,modulating gas valve train &control box.

or as

plete air heater assemblies,built to client specifications to include a "D"series Duct Burner and an air circulation fan.

SUNSRAYS "D"series burner assemblies operate directly within the heated air flow and can be located either upstream or downstream of the main air supply fans.
