The solution when faced with water hammers, noise and pulsations in:

drinking and waste water pumping stations, sanitary installations, blockage units on production plants, water tubing for fire fighting in motorway tunnels, process engineering and hydraulic installations.

OLAER dampers run without external energy. By keeping the gas securely in the bladder, no gas is able to get into the water distribution network.

Accessories

• Display and monitoring systems
  
  - Level indicator with stop valve for HYDROFORT / HYDROCHOC pressure and expansion vessels / Pressure range: up to 25 bar
    Display of gas and liquid levels
  - Magnetic level indicator with stop valve for HYDROFORT / HYDROCHOC pressure and expansion vessels
    Pressure range: up to 40 bar
    Display of gas and liquid levels, possibility of magnetic switch monitoring.
  - HYDROCONTROL volume monitoring for HYDROFORT / HYDROCHOC pressure and expansion vessels
    used for permanent monitoring of the water level in dampers.
  
• Fastening systems
  Clamps and mounting brackets as well as mounting sets secure the mounting of the dampers.
  
• Tester and pressurizer
  The VG-U unit is used to charge dampers and to test or modify the precharge pressure. It is compatible with all OLAER dampers.
  The test and charging unit can be fitted with a digital pressure gauge with peak value recording, this in addition to the standard pressure gauge. This helps precision adjusting of the precharge pressure and collect data about system pressure peaks.
  
• Ventilation and bleeder valves for drinking and waste water
  -  "Vannair" bleeder valves with high air flow rate for drinking water
  -  Simple bleeder valves for drinking water supply networks
  -  "Vannuse-Ventouse" ventilation and bleeder valves with high air flow rate for waste water.
  
• Non-return valves for drinking and waste water
  - "Clasar" return valves for use with drinking water applications
  - "Claboule" with self-cleaning ball especially designed for waste water applications.
