The Thermodynamic Trap works on the principle of difference in the velocities of Steam and Condensate. Used Mainly on Drip lines of the main steam distribution line, uses condensate pressure to open the trap and discharge the condensate and then the Flash steam formed due to the high flash steam velocity & accumulation of flash steam over disc, Device close and trap the live steam when it appears.
Thermodynamic Steam Traps are compact and lightweight and discharge condensate as and when it is formed.

UKL Ball Float Trap discharge condensate near to steam saturation temperature, which works on the principle of Buoyancy, [densities difference of Water and Steam].The rising condensate level elevates the Float open the valve and discharges the condensate, and reverse, when the level of condensate drops, valve close the trap.
The working principle of this trap can also be used as Auto Air Moisture Drain, as Air Eliminator in liquid line, as well as for lifting condensate, as a pump.
- MOC: Cast Iron and Cast Carbon Steel
- Available in Sizes: 15 mm - 50 mm
- End connections: Screwed/Socket weld ends, Flanged ends to #150 / 300 /600
- Available for working pressure up to 40 bar and Differential Pressure up to 32 Bar
Also available with Automatic Air venting [AV] and Steam lock release [SLR] arrangement
Therefore it makes sense to recycle / reuse this condensate. This function is also done by the Inverted Bucket Trap, which works on the principle of Buoyancy, [densities difference of Water and Steam].The rising in condensate level fills and envelopes the Bucket causing it to sink which open the mechanically linked valve and discharges the condensate, and reverse, when the level of condensate drops Steam enters the bucket, causes the flotation of the Bucket which close the valve and stops condensate discharge & traps the steam.
- MOC: CF8M
- Available in Sizes: 15 mm - 25 mm
- End connections: Universal connection to be mounted on ITVS
- Available for working pressure up to 40 bar and Differential Pressures up to 32 Bar
The most innovative of the bimetallic steam traps is the bi-thermostatic steam trap of balanced pressure that incorporates two antagonistic [Opposing] thermostats.
The thermostat on top consists of various bimetallic plate pairs guided by the plug’s stem, and the Lower thermostat is formed by one bimetallic sheet that leans and is guided in its edges by the body of the steam trap.
The superior [Upper] thermostat expands with the increase in temperature pressing the plug in the closing direction; at the same time, the inferior [lower] thermostat arches itself allowing the movement of the valve in the same direction, effectively resulting in the progressive strangulation of the condensate flow, till it reaches its complete closure. When the condensate temperature decreases the thermostats act inversely, consequently offering a large flow section.
The most Prominent advantages are:
- Optimum energy efficiency
- External adjustment mechanism while in service
- Possibility of repair while in operation
- Very long Life: Three times the life of the conventional Thermostatic Trap
- High reliability and versatility, Robust construction
- Resistance to water hammering, corrosive condensate, Freezing
- Automatic de aeration
- Works against high back-pressures
- Works in Superheated steam and High differential pressures
- Reduced maintenance and spare part cost
In Summary:
- Installation in any position
- This Trap can be used Bi-Directionally
- These Traps have a very long Life as compared to the conventional traps
- These traps allow discharge of condensate up to 40 Degrees Sub-cooled
These traps prevents excessive heat loss as it is filled with sub-cooled condensate as against the heat loss incurred in Thermodynamic and Ball Float Traps that are filled with Steam/Condensate at saturated temperatures.
The UKL Bi Thermostatic Bi Metallic Traps are available in pressures from 25,45, 110 and 215 Bars
Depending on the pressure and temperature conditions, the available models are: T25, T25 Ti, G25, G25 Ti, P45 Ti, G45 Ti, P110 Ti y P215 Ti.
The Smartwatch web attachment on the traps enables 24 x 7 monitoring of the Trap performance, Displaying performance in Real-time, showing Energy losses and Carbon emissions and carrying out continuous Audit and indicating potential savings of valuable resources.

UKL Trap Modules are available in two versions:
The open loop: Where the condensate is let out to the atmosphere, and consists mainly of one inlet Isolation, Bypass valves and a Steam Trap.
The Closed loop: Where the condensate connected for recovery, consist with Valves upstream and downstream isolation and Bypass, Strainer (for Ball Float), Steam Traps, Sight Glass, Non-return valve, Sight Glass, diffusers (for TD trap) etc.
Available in Carbon Steel, Stainless steel construction.
