GESTRA products

The pump trap UNA 25-PK is a modern valve which combines the function of a float trap with an additional pump mechanism. With the UNA 25-PK, you have a product that always drains your plant reliably. No matter whether a heat exchanger tends to bank up condensate in the partial or low-load range or whether an unfavourable pipe layout repeatedly leads to an accumulation of condensate in riser pipes, with the UNA 25-PK you can protect your installation and prevent thermal waterhammer.

Gravity Circulation Checks and Non-Return Valves for sanitary and HVAC (heating, venting and air-conditioning) applications

Safety Valves GSV For use with steam, liquids, and non-corrosive gases and vapours.

Deposits build up very quickly at the bottom of industrial steam boilers. The way to remove these deposits effectively is by very rapidly opening and closing a valve at the bottom of the boiler, this is called intermittent blowdown. It is an extremely demanding application which requires a robust and reliable product. The GESTRA bottom blowdown valve achieves this by opening very quickly, for just 2 seconds, producing a vacuum at the bottom of the boiler. The resulting suction removes settled sediment, known as sludge, from the bottom of the boiler. When the valve closes its design ensures tight shut-off with no leakage. Opening the valve for longer than 2 seconds has no further effect at reducing blowdown and simply wastes water.

Continual evaporation in the steam generating unit increases the dissolved solids content of the boiler water. If this is not kept to a low level, sediment and scale builds up throughout the steam system. This has a number of effects including: Reduced effectiveness of heat transfer increasing fuel costs. Increased maintenance shutdown and costs due to the requirement to service scaled up products. Production efficiency decreases as heat transfer to critical process becomes less effective. GESTRA`s BAE valves have a wear-resistant nozzle with a geometry and design that are specifically for continuous blowdown applications. It is a reliable solution that can handle arduous, continuous boiler blowdown applications at very high differential pressures.

Early detection of the presence of oil and grease contaminants in your condensate return will help to identify and prevent system malfunctions and reduce the impact on productivity. The GESTRA oil and turbidity detector is used to detect impurities in transparent liquids. The equipment is mainly employed in Industry, in the food sector, where high levels of reliability and ease of maintenance are essential for day-to-day operations. The oil and turbidity detector is suitable for monitoring untreated and treated water (gravel filters, demineralisation plants and reverse osmosis systems).

Safe and efficient monitoring of steam and hot water systems. For businesses safety, reliability, availability of steam and cost efficiency, along with effective simple plant automation and visualisation, are the top priority. Market-leading SPECTORcompact level controls achieve this through the reliable application of innovative digital technology that enables existing self-acting systems to be replaced with ease so you can upgrade your boiler to the latest standards for safety, reliability and efficiency. All measured values are transferred as standard using 4 - 20 mA signals, making the transfer process easy. You can also incorporate existing controllers by means of integrated volt-free relay contacts without any need for additional electronic control units. The integrated socket allows `plug and play` installation. With only 25% of the water level in the gauge, a 100% complete calibration can be done which saves you time, energy and water.

Safe and efficient monitoring of steam and hot water systems. For businesses safety, reliability, availability of steam and cost efficiency, along with effective and easy plant automation and visualisation, are the top priority. GESTRA has developed a digital system that can send data in both directions with SPECTORconnect which includes voltage, temperature, limit values and error messages. This provides accurate monitoring and real-time feedback so you can effectively manage and monitor your boiler.

Safe and efficient monitoring of steam and hot water systems. Safety is the highest priority when running an industrial boiler, closely followed by reliability, availability of steam on demand and cost efficiency. GESTRA`s SPECTORconnect for level limiters are market-leading in digital boilerhouse solutions. Approved to the highest safety standards, you can be sure that your boiler water level will always be within safe limits. GESTRA has designed and manufactured a digital system solution that can send data in both directions, notwithstanding voltage, temperature, limit values and error messages. This provides accurate monitoring and real-time feedback, so you can effectively manage and monitor your boiler.

Safe and efficient monitoring of steam and hot water systems. Safety is the highest priority when running an industrial boiler, closely followed by reliability, availability of steam on demand and cost efficiency. GESTRA safety temperature controls are a market-leading solution, approved to the highest safety standards, and ensuring that the boiler temperature is always within safe limits. SPECTORconnect for safety temperature controls works in combination with TRG 5 - 6x resistance temperature sensors and a separate TRV 5 - 60 preamplifier. Safe shut-down of your energy supply is achieved via a separate module, URS 60 or URS 61.  The combination of temperature probe and switch is certified to SIL 3 according to IEC 61508. You can operate the system easily and be guided by menus using the separate URB 60 operator terminal.
