Digital Thermostats Significantly Reduce Operational and Installation Costs while Maintaining Safety and Accuracy

DTS-Digital Temperature Sensor

The Challenge

Throughout the Northeastern United States, the oil and gas industries have been able to tap into the extensive underground reserves of natural gas and oil deposited throughout the geological region known as the Marcellous Shale. There are currently 30 sites with an additional four sites under construction. All 34 sites require process temperature maintenance and freeze protection from northeastern weather conditions while also lowering costs and increasing personnel safety.

The Solution

First, installation costs were lowered by using medium temperature, self-regulating cables. Thereby, reducing the number of required circuit runs. Operational costs were also lowered through the use of the Chromalox DTS-HAZ Digital Thermostat on critical lines which optimizes power through line temperature sensing.

The Chromalox DTS-HAZ Digital Thermostat also contains an SSR on/off control, a soft start capability, programmable parameters, both AC or DC alarms and a large LED display. It also contains a (Resistance Temperature Detector (RTD) sensor. The RTD sensor provides high accuracy and can maintain stability for many years without any drift.

Ultimately the Chromalox temperature management system ensures optimal process flow and viscosity of the liquefied natural gas resulting in higher plant output and capacity. Having less connections and digital alarms via the Chromalox DTS-HAZ Digital Thermostat also means less risk and a safer working environment for personnel. To ensure safety in such hazardous working environments, Chromalox meets the safety standards of Underwriter’s Laboratories (UL), Factory Mutual and the Canadian Standards Association (CSA).

The project was able to stay on schedule due to Chromalox’s turn time on RFQ as well as our fast shipment from the Chromalox Tennessee warehouse often with same/next day shipment of needed materials. 

The Benefits

  1. Significantly decreasing installation, operation and maintenance costs.
  2. Safely heating highly flammable liquid and natural gases.
  3. Implementing digital control systems to accurately monitor process and temperature.
