Innovation Center



Gruenberg has defined, developed and refined our techniques based on our many years of experience over a wide range of equipment used throughout the pharmaceutical and biotechnical industries. While our processes always include the customer’s specifications and guidelines in their entirety, we also add many value added steps, which include checks and preventive maintenance measures to improve the overall quality and reliability of our equipment. We utilize components from well-known and reputable vendors. All of these factors gives us great pride in offering the best equipment in the business. As a result, we are very happy to announce our new 1-year parts and labor as standard on Gruenberg brand equipment installed within the contiguous 48 states (1 year parts otherwise), commencing on the date of shipment.

We are also very excited to inform you Thermal Product Solutions (TPS) will extend the warranty by an additional year (up to a total of 2 Year Parts and 2 Year Labor Warranty). If Thermal Product Solutions (TPS) performs an installation (turnkey or supervised), or start-up and training service, the warranty period will commence on the date the service is completed.

If on-site warranty work is required for shipments outside the continental US, it will be billed on a time and material basis, plus expenses for travel, lodging, and meals. Outside of the contiguous 48 States, the warranty is limited to a 1 year parts only, unless there is a purchase of a TPS turn-key or supervised installation which will extend the warranty by an additional year (to a 2 Year Parts only).
