Modifications are often performed at Nutherm.

Our manufacturing capabilities include:

• Control panels and electrical systems
• Custom power supplies
• Custom electric heaters

If a part does not pass a required qualification test, a product modification is considered as a possible solution. We know from our commercial grade parts qualification experience that certain parts and assemblies will require modification. Obsolescence replacement often requires some type of modification.

Modifications have included:

• Structural integrity
• Dielectric properties improvement
• Special mounting provisions and brackets
• Changing O-rings and gasket material for harsh environments
• Special machined parts
• Special fabrications

Modifications such as polishing, coating and heat treatment are available. The following brochures that demonstrate our manufacturing and modification capabilities are available:

• Custom Panels
