IRT 3-1 PcD, IRT 3-2 PcD and IRT 3-20 PcD
1. Intended use of the product
This product serves exclusively to accelerate the drying/curing of
putty, filler,
base and clear coats. This applies to both water-borne
and solvent-based products. It´s site of use is the preparation area
and finishing area. Within the automotive industry and vehicle
repair sectors, it is used to cure small areas before polishing.The
product must not be used for other purposes than the described
drying processes. The maximum ambient temperature during
operation should not exceed 40°C.
The IRT 3-1 PcD and IRT 3-2 PcD
dryers must not be used in spray booths or within a distance of 5m from
spraying activities in order to avoid explosion risk.This prohibition is
also valid for the IRT 3-20 PcD, if not combined with the IRT Dust Cover
and Surveillance System (document 714147). Observe the regulations
described in chapter 5.1 in the installation manual (Document 713 683),
so that spraying is impossible during the drying operation.
2. Product description
The dryer is an essential aid for paint repair on small and medium
sized areas.
The easily manoeuvrable IRT 3-1 PcD, 3-2 PcD or 3-20 PcD is
equipped with one or two compact cassettes. Each cassette is
equipped with three Infra Red (IR) lamps with gold plated freeform
reflectors and a ventilator. The design, combined with a gas spring,
makes positioning of the cassette simple.The IR lamps are easily
exchangeable and the reflectors are protected against mechani-
cal damage by a mesh. The dryer has a selection of sophisticated
programs.
2.1 Particular advantages
2.1.1 Higher quality
Using the dryer when you cure putty also improves the quality of
the top coat.
The shortwave IR curing enables the coating to be cured from the
inside outwards. This prevents solvents to be trapped inside the
coating and ensures a fast and high quality curing.
2.1.2 Short drying times

2.1.3 Hi-tech shape of reflectors with short wave IR
By using
short-wave technology and gold-coated reflectors with
a high tech shape important advantages are achieved. Firstly, by
radiating only the needed areas and not heating any air, a lower
energy consumption is achieved. Secondly, a more uniform surface
temperature is obtained by distributing the energy evenly. Thirdly,
a larger drying surface is achieved. Fourthly, less radiation outside
the curing area.
2.2 Technical data
All dryers emit short wave IR-radiation with a peak at
1120 nm. The following figures show the maximum drying
area, when the respective dryer is used in 60 cm distance
from a black sheet metal.
