ゼットエンジニアリング List of Products and Services

Z Engineering Co., Ltd. aims to "contribute to the preservation of the global environment" and "realize a society where people around the world can live happily and abundantly." The steam condensate discharge system 'STEAM·Z' quickly and automatically discharges condensate and non-condensable gases (such as air) generated in steam supply pipes and heat exchangers. With no moving parts, it is less prone to failure and does not require replacement. A new model has been developed that can accommodate significant changes in steam usage (condensate volume). It has been implemented in many facilities, including thermal supply plants, building management, food factories, and tire factories. [Features] ■ Leaks only a minimal amount of steam ■ No moving parts, virtually no failures, so replacement is unnecessary ■ The condensate passing through the orifice can block the orifice hole itself, eliminating the need for an actuating valve *For more details, please refer to the PDF materials or feel free to contact us.

The "LOTUS·Z" is a compact and lightweight yet high-capacity steam condensate discharge device. Since the LOTUS·Z delivered in the 1990s has been operating continuously for nearly 30 years, it may not perform optimally if regular maintenance such as periodic inspections is not conducted. We recommend regular inspections by our technical sales team. This product is used in various locations, including petroleum distillation towers and petrochemical plants around the world, as well as breweries in Japan, helping to achieve a decarbonized and sustainable society. *For more details, please refer to the PDF document or feel free to contact us.

STEAM·Z by Z Engineering Co., Ltd. has three main distinctive features. ■ It leaks only a minimal amount of steam. ■ It quickly and automatically discharges non-condensable gases such as drain and air generated in the steam supply pipes and heat exchangers. ■ It has no moving parts, resulting in almost no failures and no need for replacement. Additionally, the warm-up time during cold starts is significantly reduced, achieving high energy-saving effects. We clearly explain the energy-saving effects during cold starts using a video.

The "LOTUS・Z" is a continuous discharge type steam condensate discharge system made entirely of stainless steel, with no moving parts at all. It is machined from solid round or forged material, so there are no welded joints. The orifice system features a structure with multiple orifice holes arranged on a single plate, and it is designed and manufactured according to the usage conditions, including the number of holes, hole diameter, and arrangement. Compared to conventional steam traps, it is much smaller and lighter, and its shape is very simple, making piping design easier and significantly reducing ancillary costs such as piping and insulation work. 【Features】 ■ Appearance and shape are short pipes with flanges at both ends ■ Compact and lightweight, installation posture and direction are flexible ■ The amount of drain that can be processed by a single unit is practically unlimited ■ Compatible with extremely low pressure to ultra-high pressure *For more details, please refer to the PDF document or feel free to contact us.

"Steam Z" is a new type of orifice trap that is resistant to failure and can accommodate significant fluctuations in drain volume. A steam trap is a device that automatically discharges unwanted condensate (drain) that occurs after steam releases heat in heat exchangers and steam piping, utilizing steam as a heat source. We are currently offering materials that include case studies on the benefits of adopting Steam Z. We encourage you to take this opportunity to read them. 【Features】 ■ No replacement needed, reducing management costs ■ Contributes to increased productivity and stable product quality ■ Prevents water hammer ■ One-fifth the weight of competitor products, saving space, etc. *For more details, please download the PDF or contact us.

"Steam Z" is a non-breakable condensate discharge device that replaces conventional steam traps. It is an orifice-type steam trap that discharges drain from the steam pipe to the outside. The continuously open circular hole (fixed orifice type) allows for continuous drainage. Its simple structure, lightweight, and compact design help reduce space, installation costs, and running costs. In the "Super High Capacity" model, we offer the "LOTUS Z" for high pressure and ultra-large capacity applications. 【Features】 ■ No valve body, making it less prone to breakage ■ Significantly reduces maintenance costs and has high durability ■ Continuous discharge prevents water hammer ■ Designed to guarantee 100% drain discharge according to the drain volume ■ Simple structure allows for small diameter and space-saving design For more details, please refer to the catalog or feel free to contact us.

Steam Z is a steam trap device that utilizes orifice theory and capillary action for steam-water separation. Z Corporation has been a dedicated manufacturer for approximately 30 years since its establishment. As a result of introducing Steam Z, switching from traditional steam traps to Steam Z generally leads to a reduction of 3-10% in costs, CO2 emissions, and crude oil consumption (energy-saving effects). Steam Z has been selected as a subsidized project by NEDO (New Energy and Industrial Technology Development Organization). For CO2 reduction in factories, minimizing steam loss, and reviewing capital investments, please consider "Steam Z." We are flexible in accommodating test installations and phased implementations, so feel free to contact us.
