Dual Compound Coater

Lower Costs and Make Your Membrane Line More Versatile

Superior Technology for Peel and Stick Production

The new Dual Compound Impregnator from Reichel & Drews is the new standard in versatility. It is designed to run two compounds on the same membrane - or run your current standard product.

With the Dual Compound Impregnator, you can run:

Non-modified asphalt and
Two different SBS compounds
Two different APP compounds
SBS and high-concentration APP

The Dual Compound Impregnator integrates saturator rolls, a squeeze roll system for removing air, two sets of calendar rolls, a patented support positioning system, edge scrapers, back coating scrapers and coating pan uniformly heated with thermal fluid. This new design includes a rear overflow weir for constant compound level and temperature, a movable gate for isolating two compounds and a unique back coating system.

Here are the key benefits you will realize with the Reichel & Drews Dual Compound Impregnator:

Better quality product and cost savings
The ability to produce both dual compound and standard membranes in the same impregnator
Better control over SBS application at high line speeds for uniform, consistent membrane thickness
Precise and easily adjustable support placement for different product requirements
Rear overflow weir to maintain constant level and eliminate crusting
Clean uniform sheet edges for superior roll winding and membrane installation
Low tension to insure minimum support distortion
Large operator access for safe, easy cleanout

To achieve your product quality and efficiency improvement goals, consider upgrading your line to include a Dual Compound Impregnator.

IMPREGNATOR SPECIFICATIONS

Dimensions	Overall length: 12'-4" approximately Overall width: 7' approximately Roll face: 55"

Entry idle roll	By Customer.

Impregnation rolls	Two (2) each 6 1/2" diameter dip rolls. Each roll has individually adjustable depth control through a handwheel rack and pinion raising and lowering system.

Squeeze roll	Two (2) each 5 7/8" diameter hot oil heated rolls, with rotary unions and flex hoses. Top roll is controlled up/down by air cylinder.

Support locating system two (2) provided	Consists of a locating idle roll positioned by a pair of raising and lowering gearboxes with handwheel. System accurately and consistently positions support within the cross section of the membrane.

Calendar rolls two (2) provided	Two (2) 5 7/8" diameter hot oil heated rolls, with rotary unions and flex hoses. Rolls adjusted through a precision worm-gear raising and lowering box. Each roll is equipped with an adjustable scraper. Entry set of calendar rolls driven by two (2) AC vector gear motors with encoders. Exit set of calendar rolls driven by one (1) AC vector gear motor. Top roll geared to lower roll. Provided with quick method of raising top roll off membrane for peal and stick product. Exit set of calendar rolls to include approx. 10" diameter transfer style inking roll with separate AC vector gear motor for back coating of the peal and stick compound.

Back coating scraper two (2) provided	Located on exit side of each set of calendar rolls. Adjustable from operator side. Heavy duty to control thickness of back coating.

Edge scraping system	Two (2) sets of adjustable edge scrapers mounted on a pivoting cross shaft. Each set of scrapers is independently adjustable to produce a uniform membrane edge as it exits the impregnator.

Framework	Heavy duty structural tubing framework complete with all items assembled.
