Industrial sectional doors made of steel sandwich panels with torsion mechanism ISD THERMALPRO

Sectional doors ISD THERMALPRO are installed in rooms equipped with refrigeration or freezing units. By hermetically insulating spaces with large temperature differences, they make it possible to maintain the microclimate created in the room and reduce heat loss. Such gates are used in production enterprises of the food industry, in warehouse complexes and sales organizations. The variety of lifting types makes it possible to ensure the closure of the cooling circuit at openings of various configurations.

Application:

Cold-storage warehouses
Food manufacturing facilities with cooling and freezing equipment

Advantages

The best thermal insulation coefficient on the market — an 80 mm thick panel, no cold bridge, profiles with a thermal break, reliable sealing of the canvas around the entire perimeter.

The door heating system along the entire circuit prevents the door leaf from freezing to the opening when operating in low-temperature conditions.

Cable break and spring break protection systems prevent the blade from falling in emergency situations.

The variety of types of gate lifts allows you to install them in rooms with any geometry of the internal space.

Equipment

Standard

Optional

Sandwich panel 80 mm thick with high-density polyurethane foam filling. The panel sheets are thermally separated by inserting an energy-flex seal, which prevents freezing of the panel joint.

The upper aluminum profile with thermal separation prevents the formation of condensation and ice in the upper part of the door leaf. The upper seal retains its elasticity at low temperatures and provides reliable sealing of the opening.

The lower aluminum profile maintains the thermal separation of the sandwich panel. The double seal levels out uneven floors and ensures good sealing. The heating wire is installed in the lower seal when selecting the “heated opening circuit” option.

Double opening sealing system: a side two-lobe seal is installed between the door leaf and the corner post, an external two-lobe seal is installed between the opening and the shield. The opening is sealed with four seals simultaneously; additional air chambers provide the most reliable sealing.

Guide systems made of 2 mm thick steel are a reliable solution with an increased safety margin.

The torsion spring mechanism, designed for 25,000 cycles, ensures the durability of the door structure.

The spring break protection device blocks the shaft, which prevents the door leaf from falling.

The cable break protection device is installed as a lower bracket on the door leaf. If the cable breaks, the mechanism is activated and prevents the door leaf from falling.

Box with installation kit, product data sheet and installation instructions.

Heating perimeter system is formed with aluminium profiles with heating cable inside which prevents door to ice-up against the opening. Bottom weather seal has heating cable as well, thus providing closed heating circuit of the door opening perimeter.

Manual chain hoist can be installed with any lift type Industrial sectional door and is used for manual opening/closing of the door.

Torsion spring mechanism has a lifetime of 100 000 cycles.

Latch lock blocks the door leaf from inside the premises. Simple and reliable.

Industrial doors can be equipped with door operators and safety devices (go to Sectional Door Automatics).

Door leaf should smoothly slide vertically along the tracks, and be properly balanced, i. e. counterbalancing mechanism should compensate leaf weight.

For opening the door in manual operation use only the door handle.

Do not lift too much force when opening/closing the door. Prevent any sharp movements of the door.

Don’t strike the door leaf or obstruct its movement.

Keep tracks and rollers clean, as dirt may prevent the door from smooth movement and cause overloading and damage of the door opener (if used).

Keep the door opening clear of any objects and litter as it may unbalance and jam the door leaf.

Installation

Mounting Options

Checking Dimensional Details

Overhead mounting. All the tracks are mounted on the headroom and side rooms inside the premise. Side room clearance — from 120 mm, with heating cable — from 150 mm.

All the necessary measurements are taken inside the premises with just a measuring tape and a water level. Every dimension should be taken at least in three points:
H — opening height (distance from floor to opening top);
B — opening width (distance between left and right side of the opening);
h — headroom (distance between opening top and ceiling) 150 mm;
b1/ b2 — left/right side room (distance between a corresponding opening edge and obstacle) 120 mm minimum; with heating cable — 150 mm minimum;
L — backroom.
When measuring Н and В the largest figure is taken for final dimension.
When measuring h, b1, b2 and L the smallest figure is taken for final dimension.
Difference of floor level along the opening should not exceed 10 mm. Make sure that mounting surface of headroom and side rooms is level. The inside perimeter of the door opening should be framed with metal or other solid material in case the surface is not not concrete or solid enough to install tracks system.

Warranty print

DoorHan warrants to the original purchaser of the product that the sandwich panels and steel profiles of the track system will be free from corrosion for a period of ten years.

New Products

The 80 mm thick sandwich panel, together with a system of warm profiles equipped with thermal separating inserts, prevents the panel from freezing.

A unique heating system for the guide circuit, which prevents the formation of condensation and ice, is installed when the gate is operated in the zone where temperature media separate.

The system for preventing the door leaf from freezing to the floor, as well as heating the guide circuit, is used when the gate is installed in an area where temperature environments separate.
