Company Overview
A.S.Controls was established in 1986, and started out as a small unit that developed level controls and valves for ammonia plants. Today, we boast of technological innovation that puts us in the forefront of the refrigeration and air-conditioning control industry in India.

We have two established brands – Castle and Subzero, both of whom have grabbed the attention, and the loyalty of several industry giants like Blue Star, Kirloskar , Reliance and others.

Our strength comes from industry experience, and more importantly, our in-house R&D team that works round the clock to keep us ahead.
Each brand has its own core technical team, and borrows specific talents from a common pool. Our approach to everything is lean and efficient. Which is how we manage to run a successful R&D team, core technical team, marketing staff, production, administration all with a low head count.
The guiding forces behind the success of the company are our values. We firmly believe, and adhere to:
• Highest levels of quality in all materials, technology and manpower.
• Use of innovation to mould technology to suit the customer's need, not the other way around.
• Creating cost efficiencies for the customer through quality efficient processes, thereby offsetting costs incurred    on high quality materials.
• Being responsible for our immediate surroundings and the environment at large.
