Altech Corp: Advanced Fan Monitoring Modules for Industrial Equipment Protection

Altech Fan Monitoring Modules for Industrial Equipment Protection

Altech Corporation has announced its new CFTD fan monitoring modules, designed to protect industrial equipment through intelligent fan current monitoring and temperature control. The series includes three models: CFTD2 (two-fan), CFTD4 (four-fan standard) and CFTDPR4 (four-fan with AC power redundancy).

Each system features precision current monitoring with configurable over- and under-current thresholds and automatic calibration that establishes baseline parameters for accurate fault detection. Models also include three-wire RTD sensor inputs for temperature monitoring with programmable set points and 4–20mA analog output for integration with building management systems. Three fault recovery methods boost operational flexibility: alarm-only, manual reset or automatic retry with 30-second intervals.

The flagship CFTDPR4 offers AC power redundancy, automatically switching to backup fans when primary power fails and ensuring continuous cooling during power faults.

Technical specifications for the CFTD modules include:
  • Power input: 100–240 VAC single phase
  • Current monitoring range: 0–750 mA per fan channel
  • Temperature display range: 0–100°C (three-digit display)
  • Temperature sensor: three-wire RTD input
  • Analog output: 4–20 mA proportional to ambient temperature
  • Operating temperature: 0° to 50°C
  • Mounting: DIN rail compatible
  • LED indicators provide real-time status updates for quick diagnostics

Siemens: SIMOVAC Non-Arc-Resistant and SIMOVAC-AR Arc-Resistant Motor Controllers

The Siemens SIMOVAC medium-voltage non-arc-resistant and SIMOVAC-AR arc-resistant controllers have a modular design incorporating up to two 12SVC400 (400 A) controllers, housed in a freestanding sheet steel enclosure. Each controller is UL 347 class E2, equipped with three current-limiting fuses, a non-load-break isolating switch, and a fixed-mounted vacuum contactor (plug-in type optional for 12SVC400). The enclosure is designed for front access, allowing the equipment to be located with the rear of the equipment close to a non-combustible wall.
