Icon Freeze Point Analyzer

At least 30°C (54°F) above the highest expected measurement point. Maximum 50°C (122°F)

Maximum 5 bar (72.5 psi)

Can be returned to pressure, provided minimum flow requirement is achieved. Typically requires a minimum 1-bar differential across the analyzer.

Minimum 12 L/H

Recommended 18 L/H

Filtered to 10 microns (μm). Sample should be ‘clear and bright’ at room temperature and contain no free water.

Required

0.2 bar (3 psi) for cell enclosure cooling (included) and optional electronics enclosure cooling.

Typically 5-10 L/H

ISO 8573.1 Class 3
ANSI / ISA-7.0.0

Potable water or antifreeze mixture.
(Do not use sea water)

Minimum 10°C (50°F)
Maximum 45°C (113°F)

Maximum 10 bar (145 psi)

Can be returned to pressure, provided minimum flow requirement is achieved.

Minimum 20 L/H
Recommended 25 L/H

100 microns (μm)

Maximum 10 cSt

Must be to atmospheric pressure.

115-230VAC 50-60Hz, Max 500VA

Unit must be located out of direct wind sun and rain.

+5 to +40 °C

0-95% RH, non-condensing.

Based on fan-less industrial PC with solid state hard drive.

17” armored glass touchscreen. The GUI is used to program the unit and display current and historical analyzer results and alarm status.

User-selectable multilingual display.

Exd certified to ATEX, IECEx, UKEx, TIIS, and EACEx standards, suitable for zone 1 or zone 2 use in gas groups IIA, IIB, or IIB+H2, with a variable T-rating depending upon application. It is also ETL listed for the USA and Canada Class 1, Div 1, groups B,C,D.

Tested and certified to IP66/IP67 (dust tight and protected from temporary total immersion in water).

Adjustable down to -100°C (-148°F)

Equal to or better than repeatability criteria of the relevant test method.

Typically, 5-10 minutes.

2 x 4-20mA (active) isolated outputs provided as standard for:
Freeze point or cloud point result (analysis mode dependant), and optionally also pour point result.

Run / Standby: reads a customer supplied latching switch to toggle between run and standby modes.
Remote Cal: reads a customer supplied momentary switch to remotely initiate a calibration cycle.
Remote Val: reads a customer supplied momentary switch to remotely initiate a validation cycle.

Alarm limits can be configured for monitored conditions, and set to be Fatal, Warning, or Inactive. Active alarms are notified on screen and stored in the alarm history table.

Fatal Alarm (NC): a general fault alarm that causes the analyzer to suspend its operation when triggered.
Warning Alarm (NC): a general fault alarm for notification only.
New Result (NO): a variable-length momentary contact to notify that a new analyzer result is available.
Data Valid (NO): indicates that the analyzer is currently running on a process stream, and that data is valid. As opposed to when in standby, or when in Cal. or Val. modes.
Cal/Val (NO): indicates that the analyzer is currently in Cal/Val mode.
Spill Alarm (NC): an alarm contact that triggers if a leak is detected in the analyzer enclosure.
All contact ratings are 24VDC 0.5A, 230VAC 1A.

Calibration Valve: provides a 24VDC signal to an external solenoid valve to switch between process and calibration samples.

The analyzer can optionally read up to four 0-10V or 4-20mA active signals. These input values can each have high/low alarm levels associated with them to trigger either of the analyzer’s general fault alarms.

The analyzer can optionally monitor up to four volt-free external contacts or customer alarms. These contacts may also be included in the analyzer alarm table to trigger the general fault alarms.

Modbus RTU or OPC over RS485 or Ethernet (TCP/IP), with optional fiber optics. Optional OPC server software.
