Chemical circulator

Chemical circulator

For temperature management of various chemical solutions! A direct circulation type temperature control device essential for wet processes.

At Nippon Excel Co., Ltd., we handle the "Chemical Circulator." This product can precisely control the temperature of chemical solutions used in RCA cleaning and wet etching. Due to its seal structure where the rubber O-ring does not come into direct contact with the liquid, there is no need to select sealing materials for each type of chemical solution, such as acidic or alkaline liquids. Additionally, the heat exchange components of the cooling and heating sections use high-purity glass-like carbon, eliminating concerns about contamination from leached metal ions, and there is no need for a surface protective film, preventing any decrease in performance due to peeling. 【Features】 ■ High-precision temperature control of chemical solutions ■ Suitable for temperature control near room temperature and highly precise due to the electronic cooling and heating method ■ Complies with international protection standard IP31 ■ Built-in leak sensor and temperature switch ■ Meets the demand for increased cleanliness associated with high mega-pit construction *For more details, please refer to the PDF document or feel free to contact us.

Shaft sealing device "Pillar Live Seal Unit No. 6300"

Shaft sealing device "Pillar Live Seal Unit No. 6300"

Are you having trouble with the shaft seals of mixers (kneaders), blenders, and dryers? It will bring stability to plant operations!

The "Pillar Live Seal Unit No. 6300" is a spring-pressurized shaft sealing device for low-speed rotating machinery. The live seal unit, designed and selected specifically for each piece of equipment, achieves proper tightening simply by tightening until the gap between the spring collar and the packing holder is zero, both during initial tightening and when re-tightening. No special tools are required. Additionally, the reduction in packing tightening force that can lead to leaks and the timing for re-tightening can be confirmed by measuring the gap dimensions. 【Features】 ■ Achieves maintenance-free operation with a gland packing and spring ■ Suitable for powder seals (dry seals) ■ Capable of maintaining stable sealing performance in response to shaft runout * For more details, please refer to the PDF document or feel free to contact us.

Reduce wear from movement! Long-lasting sealing material "Slipper Seal"

Reduce wear from movement! Long-lasting sealing material "Slipper Seal"

Protects O-rings from damage due to flexural resistance! Exhibits excellent solvent resistance and contributes to extending the lifespan of the sealing area.

The "Slipper Seal" is a product designed to prevent damage to O-rings caused by reciprocating or rotating motion by being attached to the seal sliding part. Thanks to the low friction characteristics of PTFE, rubber elasticity, and seal pressure, friction and wear are significantly reduced. It can be used with the dimensions of JIS standard O-ring grooves. Additionally, we offer sealing materials such as "Lip Seal Packing," which is effective against corrosive liquids, and "Helical Gasket," which excels in solvent and chemical resistance, suitable for piping joints in chemical plants. 【Features】 ■ Almost no change in starting resistance even after long periods of inactivity ■ No stick-slip during operation ■ Usable at high pressure without a backup ring (up to 20 MPa) ■ Usable without lubrication *For more details, please refer to the PDF materials or feel free to contact us.
