Curtain Machines

Auto Curtain 506

The Auto Curtain 506 operates curtains on a cable system by winching cable around a grooved drum controlled by a thermostat and timer.

Hardware Kits

Heavy-duty galvanized steel construction features sealed needle bearing pulleys, anti-wrap design and plated fasteners for ease of installation.

Auto Curtain 506S

The model 506S version uses a sprocket and chain drive (instead of drum) turning a pipe that runs the length of the building pulling the curtain or door drop cords directly around the pipe eliminating the need for cable (operates same as 506)

Drive Block Assembly

The Curtain Controller drive block assembly features a nylon insert in a heavy-duty powder coated weld. The removable nylon insert simplifies maintenance, decreases friction and provides wear characteristics superior to conventional brass drive blocks. UHMW polyethylene guide wheels insure smooth travel, proper alignment and stability of the drive block in the machine.

Direct Drive Gear Motor

The Curtain Controller utilizes a threaded block and drive screw directly coupled to a direct drive gear motor.

Latch Out Switches

Adjustable latch out switches can be installed in multiple locations to energize and de-energize a variety of equipment.

Limit Switches

Isolated primary and secondary limit switches allow for back-up protection. New one-piece, galvanized, liftoff cover makes for ease of service. Plastic water resistant junction box is accessible from the outside of the curtain controller.

Optional Potentiometer

Optional shaft mounted potentiometer provides an accurate and immediate signal to indicate movement and position of the drive. The potentiometer can be wired to a PF-6 inlet-positioning module to allow precise control of air inlets or curtains based on temperature rather than static pressure.

Heavy-duty Construction

Solid construction and rust resistant materials make the sprocket controller a reliable workhorse year after year.

Polyethylene Pulley Covers

Polyethylene pulley covers help stop the elements from entering through the area around the pulleys.

SP-2 Control

The SP-2 reads the static pressure in the room and adjusts any three wire drive unit until it reaches your preset requirement. With an adjustable time delay, manual adjustment and a high and low pressure alarm, this static pressure control is as complete as they get.

TC4-NV2S Control

This microprocessor based control was designed specifically for curtain machines. It can accommodate one curtain machine, one heater and one mister for example. With an easy to use digital display it can be programmed with automatic growth curves and interfaces with your PC when used with an interface. Up to four sensors can be used to average the temperature of larger rooms. Adjustable open and close times help make it the most precise curtain control for the money. It can be used with all curtain machines that do not have internal timers.
