G-LEHRS excel in simplicity, efficiency and safety.

As a result maintenance is nearly non-existing, and prices are low.

Energy saving was the determinating factor in the whole concept of the G-lehr.

User-friendliness and flexibility were important issues.

Standard Features :

• Controlled by temperature-controllers with an accuracy of 1º Celsius.
• Modular construction facilitates installation and simplifies future expansion or alteration.
• Each section has two major components : the outside case and the inside tunnel, mounted totally independent, isolated from each other with ceramic fibre insulation.
• A long lifetime thanks to the thickness and quality of the steel and the rigid construction with U profiles.
• Inside tunnel in stainless steel, especially shaped to provide optimum air circulation.
• Extremely thick asbestos-free ceramic fibre between the inside tunnel and the outside case makes the G-lehr the best isolated lehr in the market.
• The hot air circulating fans (stainless steel) are direct driven (no belt).
• Deflecting baffles for perfect hot air distribution.
• Fish bone belt support in solid stainless steel.
• Inside return belt (Outside return on demand).
• Belt min 5% chrome and stainless steel
• .
• Alarms for fans and burners gives high security.
• We guarantee perfectly welded and mounted lehrs, exact dimensions and a flawless finish.
• Only the best materials are chosen, ABB motors, Siemens servomotors, SKF bearings.
• Simple construction - Low price - Low maintenance

Natural Gas and LPG heating :

• Independent burners, each controlled by its own safety box and temperature controller.
• Proportional or high-low-off control.
• Nozzle mix adaptable to all gas pressures.
• 100 % safe, electronically controlled.
• Incoloy heat distributors.
• Peep eye for flame control
• On average 30% less consumption

Electric heating :

• Nichrome 80/20 Heating elements.
• Controlled : On/Off or proportional with thyristors.
• Newest high temperature resistant ceramic supports for heating elements.
• High temperature resistant connections between the heating elements and the power supply.
• Long lifetime.

Process Control :

• Supervises all G-LEHRS equipment by computer.
• Possibility to control non-G-LEHRS equipment.
• Extremely easy to use.
• Possibility to change the production settings on the controllers in the lehr panel or via the computer.
• Security : Changing settings on the controllers in the lehr panel, can be disabled via the computer.   

Belt Traction :

• A powerful motor with electronic speed control, fully protected, gives a wide range of belt velocity, in the safest conditions.
• The simple mechanical construction makes belt tension and belt tracking adjustment very easy, as well in mounting is in process.
• Belt is driven over a very large contact surface. The drive roller is rubberised, has a diameter of 500 mm and the belt makes contact over more than 270 degrees.
