WELDERThe technical machine data & specifications are the same as for the ROOF SEAM DETAIL WELDER & ROOF SEAM MAIN WELDER (Pos. a & Pos. b)

d) WATER CHILLER

TECHNICAL DESCRIPTION:

• Stainless steel cover
• Metal mesh air filter
• Micro-channel condenser,pure aluminum
• Water level indication ◼
• Digital thermostat with hysteresis of +/-1K◼
• Common alarm indication ◼
• Bypass for pump protection ◼
• Common alarm ◼

HYFRA eChilly series :

• Plug and Play: -easy to install
• Compact design with micro-channel technology
• Energy efficient: less powerconsumption
• Low noise: for in-room application
• Protects the environment: 60% less refrigerant

• User-friendly interface with LCD display and master control switch, all settings is made by turning and pressing onebutton.
• Possibility to set weld power, either as percentage of transformer output or as current intensity in Ampere.
• Five weld schedules that can be individually changed and renamed with up to sixteen digits.
• Weld current monitor; with possibility to set accepted deviation in percentage, monitors secondary current and displays error message if deviates from preset set point value.
• Weld current regulation that automatically compensates for current deviations during the weld cycle. The weld is performed at a frequency of 400Hz.
• Weld log that stores the last 100 error messages, even if the machine is powered off, can be very useful introubleshooting.
• Two separately weld seam counters, one that keeps track of the total number of performed seams, and one that is possible to reset.
• Two separately time counters, one that keeps track of the total number of welded minutes, and one that is possible to reset.
