Sustainable energy seal applications

Advances in storage of intermittent renewables has created need for new fluid sealing applications in electrolysis, liquid batteries, wave energy harvesting, geothermal, and turbine technology. Darcoid is actively engaged in developing improved seal performance to meet these new goals.

Critical seals in every technology platform

An area of increasing innovation, the long-term efficiency of sustainable energy installations rely on robust seal solutions.  In solar concentrators (CSP) the heliostat actuators require an environmental seal (wiper) where contamination exclusion is balanced against drag/seal friction. In photovoltaics (PV) power inverter units need long lived low closure force enclosure seals and vent seals optimized to long term ozone resistance and low compression set.  Horizontal axis wind turbine (HAWT):  gearbox and rotor shaft seals; gearless/direct drive variants, and; low closure/absolute moisture barrier access panel seals. Biomass: turbine shaft seals.  Hydrogen generation and Fuel Cells: complex manifold and flow channel seals, membranes and diaphragms optimized for electrolysis, KOH potassium hydroxide, closed system long-life low-compression set and low permeation. Our technical team will quickly focus on the critical performance drivers for your application to drive quickly to a recommendation.

Solar Panels - Seals

Seals optimized to your performance spec.

In new product design processes, the integration of the sealing element(s) are frequently overlooked or considered an afterthought. Fixing a nonfunctioning seal AFTER your enclosure injection tooling is complete puts all kinds of strain on your project deliverables.   While we’ve fixed plenty of these late-stage problems it’s always prudent to bring us in before you cut that tooling PO. Engage with a Darcoid applications engineer as early in your project as possible to assure your project timeline and budget stay on track.  Our technical team at Darcoid is driven to help you develop the best possible seal for your unique application. 


Predictable performance with every build? Control for Seal Performance Creep.

A critical part of your program’s success is making sure the seal that gets assembled in your product 4 or 5 years from now performs the same as the seal you qualify for production release.  Small omissions or assumptions in your control specs can create major headaches in the future..  Darcoid Applications Engineers will teach you how to control Seal Performance Creep so you can rest easy and focus on developing your next great thing!
