Z Engineering Co., Ltd. is a company that handles the orifice-type drain discharge system "STEAM·Z." We have overcome the shortcomings that were considered weak against fluctuations in drain volume. When the maximum discharge drain volume is set to 100%, it does not leak steam even if the drain volume decreases to 25% (1/4). It almost does not leak steam even if it decreases to 12.5% (1/8). Based on the manufacturing and sales of "STEAM·Z," we aim to achieve a decarbonized society. We will work on quality improvement through obtaining ISO 9001 certification. *It has been selected as a recipient of subsidies from NEDO (New Energy and Industrial Technology Development Organization). *We received the Edogawa Ward Industrial Award for the fiscal year 2016.
