Why KT Series is the Choice for PET Blowing & Laser Cutting
Challenges Facing Medium-Pressure Air Systems
- High operating cost caused by high oil consumption of medium-pressure compressors.
- Valve plate bending, short service life and frequent maintenance downtime.
- High exhaust temperature and carbon accumulation under long-time heavy load operation.
- Impure compressed air contaminating laser lens and PET mould.
- Single air volume control mode unable to match fluctuating gas demand.
- Risk of liquid strike due to poor timing drainage control.
How KT Series Optimizes Your Production
- Patented combination valve design reduces oil consumption below 0.143 kW/h.
- Swedish stainless steel valve plate + Japanese spring steel prevent deformation and extend lifespan.
- Custom intercooler & optimized airflow design keeps low exhaust temperature and reduces carbon deposit.
- 5-stage precision filtration + stainless steel freeze dryer provides ultra-clean compressed air.
- Four air volume control modes plus optional intelligent controller adapt variable gas demand.
- Adjustable timed drain valve prevents liquid strike and supports continuous running.
- Redundant safety protection and zero-pressure start to secure stable 24/7 operation.
Engineered for High-Pressure Industries
○ Valve materials are made of Sweden stainless steel band.
○ In order to ensure that air compressor highly reliable, using a redundant design principles, setting multiple protection measures: unloading, down drain, exhaust, ensure that the zero-pressure start.
○ Timed drain valve: Drainage and drainage at a time interval can be adjusted. Ensure that the captain of an air compressor runs continuously between regular drainage, effectively preventing water too much liquid strike accidents.
○ High reliability and long maintenance period, very low fuel consumption, low energy consumption and so on, greatly reducing the overall general operating costs.
Combination valve patented technology
- Kotech combined air valve is the special kind of high efficient energy-saving and long life new combination air valve.
- Structure by into trachea-shaped valve and exhaust valve combinations, the main features below :air through the intake manifold valve cavity, along the tangent of the valve flow, impact of approximate straight lines, air valves and flow resistance greatly reduces, so it could provide low noise, long service life.
- Because of the inlet valve inside the vertical spatial distribution, inlet of the valve flow area increased, the valve flow rate and lower drag coefficient, aspiratory volume increase volume efficiency, reduced energy consumption.
- Intake and exhaust valves is the reed valve and strip-type valves fixed unlimited free elastic beam opening and closing movements, without friction and clearance volume small so kotech combined air valve has excellent dynamic performance and reliability.
- Fuel consumption per hour less than 0.143/kw.
- High reliability and long maintenance period, very low fuel consumption, low energy consumption and so on, greatly reducing the overall general operating costs.
Design Features
1. Powerful big head design, good material utilization, strong design of main components, head size and weight are bigger than other manufacturers, high safety, low speed, especially suitable for heavy load, long term continuous operation, extremely high reliability and super long life.
2. Special heat dissipation design and airflow design, low exhaust temperature, not easy to accumulate carbon, high efficiency.
3. Adopting an annular valve group design, the valve plate material is Swedish stainless steel valve plate, and the valve group spring material is special spring steel wire imported by the valve from Japan, the valve plate does not bend during operation, which improves the performance of the valve. The life index is particularly good.
4. The piston ring is made of imported Japanese fittings, which is durable and non-oil-contaminated.
5. The crankshaft adopts high-frequency quenching, which is particularly wear-resistant.
6. The related moving parts are precisely balanced, the movement is particularly stable and the noise is particularly low.
7. The air filter element adopts imported filter paper, which has a good filtering and noise reduction effect and is durable.
8. The front end cover is specially designed with an oil barrier structure, the breathing valve is not out of oil, the oil consumption is particularly low, and the body is clean.
9. The flare angle of the exhaust copper pipe is reasonably designed and protected by a protective cover to avoid rupture and air leakage.
10. pressure switch, contactor, thermal relay ‘Schneider’ and other imported brands to ensure reliable control and protection.
11. In terms of air volume control, there are four modes for users to choose from: full-automatic air volume control, full-automatic electric control, dual-use air control and electric control (manual switching) and intelligent control (automatic switching of electric control according to the amount of air consumption) to meet the different needs of users.
12. An intelligent controller can be installed optionally to meet the user’s complex gas conditions.
13. because of the relatively high-pressure ratio of the medium-pressure machine, a specially designed intercooler with a strong cooling capacity is used to maintain a low exhaust temperature.
Frequently Asked Questions
The KT series is specifically engineered for industries requiring medium pressure (20-40 Bar), such as PET bottle blowing, metal laser cutting, and high-pressure leakage testing. Its integrated design ensures a stable air supply for 24/7 industrial production.
We use a "powerful big head" design with premium materials. Key components like the valve plates are made of Swedish stainless steel, and the piston rings are imported from Japan. These high-spec parts allow the machine to operate at lower speeds, significantly extending its service life and reducing wear.
Yes. The KT series features a specialized heat dissipation and airflow design to maintain low exhaust temperatures. This prevents carbon buildup and ensures the system remains efficient and safe during long-term continuous operation.
Absolutely. Our integrated system includes a stainless steel plate freeze dryer, a 5-stage precision filter, and a centralized electronic sewage disposal system. This multi-stage treatment ensures the air is dry, oil-free (low oil carryover), and clean enough for sensitive laser cutting lenses.
The KT series utilizes our patented Combination Valve Technology. This design reduces air flow resistance and increases suction volume, leading to higher volumetric efficiency. The fuel consumption is exceptionally low (less than 0.143/kw), greatly reducing your total cost of ownership (TCO).
We offer four control modes: full-automatic air volume control, electric control, dual-use (manual switching), and intelligent control which adjusts output based on actual air consumption. You can also opt for an intelligent controller for more complex gas requirements.
Thanks to the high-frequency quenched crankshaft and wear-resistant parts, the KT series has a very long maintenance interval. Regular checks on air filters and oil levels are the primary requirements. We provide a full range of genuine spare parts to ensure your system remains at peak performance.
