Tor Saturn Programmable Controllers
Smart Direct Digital Controllers (DDC) — Saturn AHU Controller and Saturn Universal Controller — engineered for precision HVAC automation, VFD fan control, and industrial process loops.
Precision Climate & Automation Control
The Tor Saturn Controller Series provides high-density input/output (I/O) control for building management and HVAC systems. Available in dedicated Saturn AHU Controller and Saturn Universal Controller variants, these units execute localized closed-loop PID control for temperature, relative humidity, air static pressure, and motorized valve positions.
Integrated by SS Exim into custom panel enclosures across Mumbai, Pune, and Bangalore, Tor Saturn controllers connect directly to return air temperature sensors (Tor Mercury), differential pressure transmitters, VFD fan drives, and Modbus networks.
Tor Saturn Family Options
Tor Saturn AHU Controller
Dedicated HVAC AutomationSpecifically programmed for Air Handling Unit (AHU) automation. Includes dedicated routines for supply fan VFD modulation, chilled water 2-way / 3-way valve positioning, fresh air damper control, and dirty filter alarm differential sensing.

Frequently Asked Questions — Tor Saturn Controllers
What are the primary variants of the Tor Saturn Controller?
The Tor Saturn family includes the Saturn AHU Controller (dedicated to Air Handling Unit fan speed, valve, and filter control) and the Saturn Universal Controller (flexible DDC controller for general building automation).
Can Tor Saturn controllers operate independently without a central server?
Yes. Saturn controllers store local PID logic in non-volatile flash memory, enabling autonomous AHU and valve regulation even if central BMS server connection is lost.
Does SS Exim supply complete pre-wired control panels?
Yes, SS Exim custom fabricates LT control panels containing Tor Saturn controllers, circuit protection, VFDs, and relays for easy plug-and-play field installation.
