Large manufacturing sites routinely operate hundreds or thousands of mechanical steam traps, with industry data consistently showing annual failure rates of approximately 10%. Failures are unpredictable and can occur open or closed, leading to live steam losses, waterlogging, poor heat transfer, and process instability.
Maintaining performance requires a rigorous programme of continuous surveying, monitoring, and replacement. In practice, this level of intervention is rarely sustained, resulting in ongoing energy losses, rising maintenance costs, and reduced system reliability, conditions that have long been accepted as an unavoidable feature of steam systems.
The GEM Steam Trap is a full venturi steam trap that removes the mechanical failure inherent in conventional designs. With no moving parts, GEM Traps do not wear, stick, or fail open, enabling stable, long-term performance across real-world industrial operating conditions.
By eliminating live steam loss and performance deterioration, full site conversions typically deliver payback in under two years while providing sustained reductions in fuel consumption, carbon emissions, and maintenance burden from day one.

Quality, experience, global presence, and service. Thermal Energy International has multisite, international project capabilities. Retrofitting with GEM Traps is straightforward and impactful, delivering carbon reduction targets.
GEM Steam Traps are designed to operate reliably across variable loads, pressures, and demanding environments.
The staged venturi throat regulates condensate discharge without backing up condensate or passing live steam, improving process control and heat transfer.
TEI’s advance patented three stage filtration system is employed on smaller orifice traps required for line drainage, trace heating and other low capacity steam trap applications reducing any risk of plugging from dirty steam.
Thermal Energy International takes responsibility for the correct sizing, manufacture, and commissioning of every GEM Steam Trap. Correct sizing ensures a stable condensate seal is maintained at the venturi throat, preventing erosion and wire-draw while maintaining performance over the lifetime of the installation.
Each trap is manufactured as a single-piece stainless steel body, eliminating internal joints, leak paths, and removable inserts.
This engineered approach ensures energy savings and reliability are maintained for decades — many GEM Traps continue to operate reliably after more than 20 years in service.
Elevating steam trap replacement from an OPEX to a capital investment enables a one-off permanent site conversion. This realises savings and efficiencies earlier as a step change, and is the most impactful way to implement GEM Trap projects.
GEM Traps eliminate the dominant failure mechanisms found in mechanical steam traps, therefore savings are delivered immediately. Projects can be implemented over a short timescale without major plant disruption.
Mechanical steam traps typically last two to five years, with steam losses that can exceed their purchase price in a single year.
In contrast, GEM Steam Traps deliver decades of reliable service with no ongoing replacement cycle.
With typical paybacks of less than two years and a ten-year performance guarantee, GEM Traps provide a low total cost of ownership and no recurring replacements. Long-term operational stability, energy savings, and risk reduction.
From initial site survey and application-specific sizing through to commissioning and long-term service options, Thermal Energy International’s engineering team provide full support.
Thermal Energy take full responsibility for correct application and ongoing performance, providing a 10 year guarantee. This ensures certainty from day one and continuity as operating conditions evolve.
GEM Steam Traps operate using a multistage venturi throat that continuously discharges condensate as it is formed. Unlike mechanical traps, GEM Traps do not rely on an open/close cycle. Condensate flows continuously through the configured venturi throat, maintaining a protective condensate seal that prevents live steam loss while avoiding condensate backup.
The design of the GEM Trap eliminates the primary causes of failure in mechanical steam traps while delivering inherently higher energy efficiency and long-term reliability.
Superior Design
No failures - no moving parts to wear, stick, or fail.
Continuous Discharge
No Cycling - no live steam is lost in operation and process control improves.
Full Venturi Throat
Stable operation across variable loads - multistage venturi throat comfortably accommodates industrial process running loads.
Single Piece Body
No inserts - full traceability back to the sizing calculations, process information and installed location.
Patented Filtration System
All smaller, low duty orifice traps are protected by a patented 3 stage filtration process.
These case studies show how converting to GEM Steam Traps delivers meaningful financial and operational impact. Customers have reduced steam energy use by 10 to 20%, achieved payback typically within two years, improved condensate return and strengthened process stability, while lowering maintenance demand and carbon emissions.
Our case studies are drawn from a range of facilities and documented project outcomes illustrating that replacing mechanical steam traps with GEM technology delivers quantifiable performance in live industrial environments.
