The LAB9.50 dehydrator provides continuous dry air flow up to 1000 l/h with a dew point better than -45°C. Output pressure can be set in the range from 10 kPa to 60 kPa.

The LAB9.50 achieves reduced mechanical wear and noise and therefore a long lifetime by output pressure measurement, microprocessor control and pump speed regulation. Pumps speed control avoids mechanical pressure regulators thus eliminating undesirable pressure losses and a worse response to
plant air flow regulation.

Two drying chambers contain the desiccant and dry airstream by adsorption process. The chambers
operate on alternate cycles so while the first chamber dries, the second one regenerates the desiccant by
heating and backwashing with a small reverse dry air flow.

The dehydrator also adjusts the switching interval between the two drying chambers according to the
amount of dry air supplied to the plant.

This technology reduces overall power consumption.

The following devices are available on the front panel:

  • 2×16 LCD
  • two function keys
  • two leds (power on, alarms))
  • on/off outlet valves

The LAB9.50 provides front access keys to set the operating pressure at any time.

Output pressure measurement and hour meter values are indicated on the LCD.

The basic version offers low pressure, high pressure, high humidity, power and system failures alarms. All alarm messages are locally signaled and remotely signaled by SPDT relay.

Available Options:

  • remote control through SNMP protocol and HTTP interface by a 10/100 Mbit Ethernet interface
  • digital flowmeter with data showed on the display

Power supply and alarm remote connectors, outlets with hose-tail fittings are available on the rear panel.

The LAB9.50 always includes wall, 19” and ETSI N3 rack mountings.
