Kofloc Model 3660 Mass Flow Controller

Description

The Kofloc Model 3660 stands out in the Kofloc lineup for its exceptional balance of speed and stability. The internal control circuit uses an advanced algorithm to drive the solenoid valve, achieving a response time of under 2 seconds to reach a stable set-point. This makes it ideal for batch processes or applications where gas flow needs to be adjusted frequently and precisely. Built with high-quality Stainless Steel (SUS316) wetted parts, the Model 3660 is compatible with a wide array of non-corrosive gases. It operates as a “closed-loop” system: it receives a set-point signal (usually 0–5V DC), measures the actual flow, and automatically adjusts the valve position to eliminate any error. This level of automation removes the need for manual monitoring and ensures that your chemical reactions, furnace atmospheres, or analytical samples are consistently managed 24/7.

Kofloc

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.
