Applications in hazardous areas require equipment specifically designed and certified for the relevant environment.

Schischek Explosion-Proof Actuators provide actuation options for HVAC and industrial systems installed in areas where explosive gas or dust atmospheres may be present.

For example, Rotork’s Schischek-related ExRun linear actuator range is designed for hazardous areas including Zones 1, 2, 21 and 22 for applicable gas and dust environments.

These actuator systems may be used for applications including:

• Chemical processing facilities
• Oil and gas installations
• Industrial ventilation
• Paint and solvent areas
• Hazardous storage locations
• Process plants
• Specialised HVAC systems

Selection must always be based on the required hazardous-area classification and applicable certification.

Temperature and humidity measurements are important for maintaining stable environmental conditions within HVAC systems.

Schischek sensor solutions include devices intended for room and duct applications.

The ExPro-C range, for example, supports temperature and/or humidity measurement in hazardous areas and can be used for room or duct sensing.

Applications can include:

• Industrial HVAC
• Clean environments
• Warehouses
• Manufacturing facilities
• Process ventilation
• Hazardous-area HVAC

Differential pressure is commonly monitored within ventilation systems to assess airflow, filters and duct conditions.

Schischek pressure sensor products provide monitoring for suitable HVAC applications.

Products such as ExCos-P and RedCos-P are designed for differential pressure measurement in hazardous environments, depending on the relevant zone classification.

HVAC automation requires dependable control of air and fluid movement throughout a building or industrial facility.

Schischek actuator solutions can support automation of:

• Dampers
• Air handling units
• Heating valves
• Cooling valves
• Ventilation systems
• Fire and smoke systems
• Process air systems

Depending on the application, rotary or linear actuation can be selected.

Actuators control equipment, but accurate building and process automation also depends on reliable measurement.

Schischek HVAC Sensors provide sensing technologies for monitoring environmental and process conditions.

The portfolio includes solutions for parameters such as:

• Temperature
• Humidity
• Differential pressure
• Airflow-related measurement
• Other HVAC process variables

Rotork’s Schischek sensor portfolio includes Pro temperature/humidity sensors and Cos-series pressure and transmitter solutions for both safe and hazardous environments.

A major advantage of having both actuators and sensors within the product family is the ability to support multiple components of an HVAC automation system.

Sensors measure operating conditions while actuators respond to control commands by adjusting the position of valves or dampers.

This makes Schischek particularly relevant to industrial HVAC systems where environmental conditions, safety classifications and dependable automation all need to be considered together.
