Hinged double leaf door

Basic information

Hinged double leaf doors are used when doorway width is over 1400 mm. Such openings are used in cold rooms designed for storing and freezing large-sized products or packs of products. With one leaf open, hinged double leaf doors may be used as a regular hinged door, and with both leaves open, HDLD allows you to transport large-sized loads on trolleys.

Hinged double leaf doors are used in the following facilities:

• Industrial medium and low temperature cold rooms
• Refrigerating warehouses
• Facilities, where high temperature conditions are required
• In 80% humidity and temperatures from -35...+45°C with a short duration of humidity
• Storage facilities for large containers and products
• High traffic areas
• Rooms where goods are carried manually or transported by trolleys
• In places where there is no dust, sand, or other loose materials

Double Leaf Refrigeration Door options

Double leaf refrigeration doors with or without threshold

In non-threshold door configuration, a 15948 EPDM sealer is attached to the bottom of the door leaf. If non-threshold cold room maintains low or shock-freezing temperature conditions, it is recommended to add insulated threshold made of stainless steel.

HDLD with threshold

HDLD without threshold

Double leaf refrigeration door with left or right opening. The opening leaf is on the right by default

Both door leaves may have different width, but not less than 550 mm, and can be produced according to your individual project. Door leaves are produced with equal width by default.

Medium and low temperature refrigeration doors

Door sizes

Door leaf thickness, mm: 80, 100, 120
Opening height: up to 2400 mm in standard and up to 3000 mm in R series with locks and hinges by Rahrbach, Germany
Opening width: up to 2400 mm in standard and up to 5000 mm in R series

You may see standard hinged double leaf door dimensions in the table below

Temperature conditions

You may use HDLD without additional heating cables for medium temperature cold rooms (when required temperature is above 0°C). In this case we recommend to use 80 mm thick door leaf.

For freezing cold rooms with temperature from 0°C to -20°C we recommend you to choose 100 mm thick door leaf and additional heating cables for door frame. You can also order insulated threshold made of stainless steel for non-threshold refrigeration doors. In low temperature cold rooms additional heating cable is installed into the sealer of the main door leaf.

For shock freezing cold rooms with temperature conditions below -20°C to -35°C we recommend you to choose 100 mm thick door leaf. It is required to equip the door with heating cable for both door frame and door sealer. Insulated threshold made of stainless steel is installed into the floor in case of non-threshold doors.

Door leaf

The door leaf, including the ends, is made of 0.5 mm thick steel sheet, which (unlike end plastic profiles) allows to withstand mechanical shocks and loads. Rigid polyurethane foam with a density of up to 50 kg/m³ is used as a core.

Metal ends give the doors additional resistance to side impacts that are unavoidable during operation.

Depending on the degree of aggressiveness of the working environment, we produce sliding door leafs with the following types of metal:

• Galvanized steel, painted with white polymer paint (RAL 9003). You may order the door leaf in any color of your choice according to the RAL catalogue
• Galvanized steel, unpainted
• Aisi 430 stainless steel for non-food facilities
• Aisi 304 stainless steel for food facilities
• Food Safe laminated steel

The doors are wrapped in 50 μm thick film to prevent damage when transporting or mounting, the film is easily removed after the installation.

Hinged double leaf doors are equipped with tape-like sealing gaskets made of based on EPDM rubber with a layer of sticky reinforced adhesive protected by tread paper. Sealers in hinged double leaf doors are used at the bottom of the door leaf in the non-threshold doors and along the perimeter of the leaf in all options.

PH Insulation door frames are produced of 2 mm thick steel sheet and painted with the color of your choice or standard white RAL 9003. PH Insulation doors and frames are fully customizable with a choice of colors and steel: stainless steel frame AISI 304 for food facilities or AISI 430 – for non-food ones.

Door frame is mounted to the outer wall of the doorway with the mounting kit that is included in the door package.

Door frame size depends on door opening dimensions:

• Door frame width = opening width + 240 mm;
• • Door frame height = opening height + 120 mm + threshold height

Door hardware

You can order 2 options of hinged double leaf door hardware

Standard series:

R series:

German Rahrbach lock is installed onto refrigeration doors with height up to 5 meters. The required level of insulation is provided with additional closing point.

The fixed door leaf is closed with a special handle made by German manufacturer Stuv. When you turn the lever, the door is fixed simultaneously with two metal rods up and down, which makes closing simple and convenient.

Door hardware mechanisms are made from metal and protected by plastic cover. Lever type handle is wear-resistant, extends the service life of the structure.

Additional locks are installed on doors with a height of more than 2350 mm, which ensure steady clamping.

1. Rahrbach door hinge for HDLD R
Designed for hanging the door leaf onto the frame (opening). The position of the door leaf is adjustable in 3 dimensions (3D). The hinge body is metal. The hinge provides a lift of the door leaf when opening in order to prevent the bottom sealer from rubbing on the floor

2. Rahrbach handles/lever kit with lock and the response part of the lock
Consists of internal and external handles. Rahrbach lock is made from frost-resistant composite materials. In accordance with European safety requirements, the lock is equipped with an anti-lock device that allows you to open the door from the inside if it is accidentally locked. The handle mechanism is made of metal and protected by plastic cover. The handle is installed on doors with a thickness of 80, 100 and 120 mm.

3. Rahrbach additional lock
The Rahrbach lock is used as an additional closing point for steady clamping of the door leaf. Additional lock is installed on the doors with 2350 mm and more height at a distance of 1000 mm from the inner handle or lever.

4. Stuv handle kit for auxiliary door leaf
Consists of the handle and rods with stainless tips. Designed to fix the stationary leaf of double leaf doors. This kit is included in basic configuration of HDLD R.

5. Door leaf

High quality PUR rigid polyurethane core with density of up to 50 kg/m3 provides thermal insulation.

6. Fermod 67 double rubber gasket
Double rubber gasket made by French manufacturer Fermod is designed for sealing the door leaf of hinged doors with an opening.

7. Door frame
The rigid overhead profile frame is made of 2 mm thick cold-rolled steel sheet with, painted with powder paint.
