InterDam Merford, your supplier of cost-effective STANDARD blast- and fire resistant walls- and doors, is happy to introduce to you an innovation that dramatically reduces the opening force required for heavy duty sliding doors: the Ergo Latch©. This latest innovation ensures a maximum opening force of 5 kilograms.

InterDam Merford has recently developed this heavy duty lock with a forced opening mechanism (the Ergo Latch©) for an easy opening of heavy duty sliding doors.
Sliding doors can now be provided with the Ergo Latch© that mechanically engages when the door is manually opened. The mechanism is of heavy duty design, fully made of stainless steel and perfectly suits your applications in a harsh offshore/onshore environment.

With this innovation, pneumatics are no longer a must according to the NORSOK rules!

InterDam Merford provides spare parts for maintenance on on- and offshore fire- and blast doors. Many of the spare parts, such as top track rails, support rollers or hanging brackets and bolts were originally supplied by NorDam and DAMPLAAT. Staff of NorDam and DAMPLAAT is now working under the name of our current company, InterDam Merford.

Blast relief Walls and Hatches
InterDam Merford also provides blast relief walls and blast relief hatches
Blast relief walls and blast relief hatches are often fixed with break bolts. A break bolt is a fastener that breaks when subjected to a pre- determined load.
More reliable fixings for this kind of walls are those that collapse by bending open; that is at the load whereby the yield point is reached. IDM offers both types of fixing methods.
