A.S.Controls

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.

In the world of complex machineries, controls are the heart of every device. They keep tabs on all parameters required for optimal functioning, report problems, assist maintenance crews, and of course, prevent break downs.

We, at AS Controls, create products that enhance your product, save maintenance and repair costs, improve product life, and create a much better end customer experience.
A majority of our products are aimed at the refrigeration and air conditioning industry. Our two product lines covers two major categories:

	Sub zero: Digital controls for temperature, humidity, and pressure.

	Castle: Level controllers, Shut off Valves for ammonia, solenoid valves, strainers, ball valves
	(LCB,S/S, Brass) and other accessories for the refrigeration industry.

All products are manufactured in-house, as a quality control measure.


	Our comprehensive quality program covers the production process from start to finish:

		Quality Components: All components are sourced from the ‘best in the field’ suppliers and quality
		tested on
		arrival. We are one of the few organizations in India who have an in-house facility for EMC (electromagnetic compatibility) tests.
		Technology: Our in-house D&D team is constantly evolving new, more efficient means of production and
		assembly. In addition, we employ industry best practices wherever applicable.
		Sturdy and intelligent design: Our D&D team constantly works on improvements to existing technology
		and design to reduce interference, increase efficiency, and lower costs without compromising on quality.
		We have learnt from several customizations, and now incorporate these and other innovations into our
		product lines.
		Adherence to design specifications: We have quality and adherence checks at every production
		milestone. All finished products also go through rigorous testing before release to customers.


	Our in-house D&D team spans both electrical and mechanical fields, giving us the advantage in developing products suited to the customers’ need across both fields. The electronic controls team is proficient in the areas of PCB design (Single sided, double sided, multilayer boards), Hardware design (analog, digital, mixed signal) and Embedded software (Assembly language and C for micro-controllers). The mechanical arm is adept in the design of valves and other items essential to Ammonia and Freon based products. Our talent pool, backed by in-house machinery and 3D software, allows us to create and test prototypes in a much shorter design cycle.
