Gas pressure regulator R51

The spring-loaded gas pressure regulator R 51 has the function of keeping the outlet pressure of a gaseous medium constant within permissible limit values, independently of the effect of interferences, such as changes in the inlet pressure and/or in the gas flow, in the connected regulating line on the outlet side.

LET The CUSTOMERS SPEAK FOR US

Customer from: Russia Engine: Wartsila 34SGTechie Model: TISS9836

We used Champion FB78WW at first, but Techie's bridge design spark plugs have been brilliant on our Wärtsilä 20V 34SG setup. They have the same service life (around 2000 hours) but are much lower in price.

Customer from: USA Engine: Jenbacher J416 Techie Model: TISS98P3

Since 2022, we have relied on Techie Power Parts. Previously, we used Jenbacher original spark plugs (part number 462203) in our Jenbacher J416 CHP power plant. After testing, it was clear that switching to the TISS98P3 was the right decision. The Techie 98P3 achieves 8,000 engine hours at only half the price of the original.

Customer from: Bangladash Engine: Guascor 952 KW Techie Model: TISS9810

আমাদের গুয়াসকোর ৯৫২ কিলোওয়াট ইঞ্জিন যখন আইল্যান্ড মোডে লোড নিয়ে চলে, তখন TISS9810 স্পার্ক প্লাগগুলো অসাধারণভাবে কাজ করেছে। উচ্চ লোড এবং দীর্ঘ সময় চলা সত্ত্বেও আগুন ধরানো স্থিতিশীল এবং নির্ভরযোগ্য রয়েছে, যা ডাউনটাইমের ঝুঁকি ব্যাপকভাবে কমিয়ে দিয়েছে। টেকির টেকনিকাল সাপোর্টও আমাদের রক্ষণাবেক্ষণ পরিকল্পনা উন্নত করতে সাহায্য করেছে—প্রকৃতপক্ষে বিশ্বাসযোগ্য!

Customer from: Russia Engine: MTU 4000 Series Techie Model: TISS9865

Simply the best replacement plugs on the market. Tried them, won't use anything else now. The longevity is unmatched. For TISS9865, already use 4,000 hours and still going strong on our MTU gensets.

Customer from: Thailand Engine: GUASCOR SGLFD560 Techie Model: TISS9825

Our construction equipment operates in extreme, dusty conditions. Your team helped us select the perfect plug for our specific engine model and operating conditions. It is replace for Bosch 7305, these spark plugs are still in good condition and running well today.

Customer from: Italy Engine: MWM TCG2020 Techie Model: TISS9888

Performance is everything in our line of work. These plugs have provided noticeably smoother cold starts and more stable operation under load for our MWM engines. The improvement in combustion efficiency was clear from the reduced exhaust smoke.

Customer from: Nigeria Engine: Cummins Techie Model: TISS9825

I was skeptical at first, but Techie's plugs have been brilliant across all our Nigerian sites—from Lagos to Abuja. In our power plant's generators, they last way longer than others we've tried—around 4000 hours—and they're still going strong. We keep coming back for more.

Customer from: Nigeria Engine: MWM TCG2020 Techie Model: TISS9888

Running our operations in Lagos, where the grid is unreliable and the air is thick with humidity, we put our MWM TCG2020 gensets through hell. I was deeply skeptical that any prechamber plug could handle it, but Techie’s have been nothing short of brilliant. They’ve withstood the constant stop-start cycles and delivered over 4,000 hours of flawless, efficient operation. For reliability in Lagos conditions, Techie is the only choice for our MWM engines.
