Operating Manual: SU105U-86˚CUltra Low Storage

1. Introduction

1.1 – Description

The Stirling Ultracold SU105U FPSE Ultra Low Temperature (-86°C) Freezer uses

proven M150A free-piston Stirling engine (FPSE) technology to provide high eﬃ-

ciency, deep-temperature cooling.

1.2 – Applications

The SU105U freezer is designed for long-term storage of materials with ultra low,

well-regulated temperature storage requirements, such as found in clinical and bio-

logical laboratory and testing settings.

1.3 – Documentation

1.3.1 – Operating Manual

• This operating manual describes all aspects of receiving, installing, use, moving and

storage of the Stirling Ultracold SU105U Freezer. More detail on speciﬁc aspects of

operation of the freezer is available via online supplementary documentation.

• Performance of the freezer is controlled by electronic logic that is programmed

through a touch screen interface termed the Swift Graphical User Interface (GUI).

This operating manual describes use of the Swift GUI, and the appended Swift GUI

Supplement expands that description with pictorials of each screen and option.

User Advisory:

Deep temperatures are dangerous, use proper precautions when operating ultra

low temperature freezers. This ultra low temperature freezer is intended for storage

of frozen sample product or vials at deep temperatures. Stirling Ultracold, Division

of Global Cooling, Inc. cannot be held responsible for damages or loss of stored

product attributed to unintended use. In no case will Stirling Ultracold, Division of

Global Cooling, Inc. be held liable for loss of stored product resulting from electrical,

mechanical or structural failure. As with any ultra low temperature freezer, appropri-

ate back-up and redundancy considerations are the responsibility of the user.

1.4 – Organization of this Operating Manual

This manual is organized as follows:

• Unpacking and installation

• Set-up

• Operation

• Transporting and moving

Please note that precautions and safety instructions are part of each section of the

manual, and must be observed to avoid damage to the freezer or harm to its users.

1. Introduction

803.2012.1

Operating Manual: SU105U-86˚CUltra Low Storage

2. Features of the SU105U freezer

2.1 – Free-Piston Stirling Engine (FPSE)

The SU105U Ultra Low Temperature Freezer uses the

state of the art Stirling Ultracold Model M150A free-

piston Stirling engine (FPSE) to provide high eﬃciency,

deep-temperature cooling. No HCFC or CFC refrigerants

are used in the M150A and SU105U. The M150A Stirling cycle engine uses approxi-

mately 2 grams of helium gas as a working ﬂuid. The secondary coolant loop uses

60 - 65 grams of refrigerant, R-508B (“SUVA® 95” *), as a working ﬂuid.

2.2 – Cabinet Design Features

The cabinet is VIP insulated with polyurethane foam support providing an internal

volume of cabinet approximately 105 liters. The blowing agent is HFC R245a. A

locking cam door latch ensures door gasket compression when closed. Door sealing

consists of three gaskets and is factory replaceable. A door defrost minimizes water

or ice deposition on the gasket interface.

2.3 – Temperature Monitoring Features

Two resistance temperature detectors (RTDs) measure the internal cabinet tempera-

ture of the SU105U. One provides input to the FPSE controller and the other provides

input for the Swift GUI display and for reporting and logging. The display RTD may be

user calibrated through the Swift GUI. The Swift GUI provides a door open timeout

alarm and monitors the temperature reporting RTD for excursions beyond high and

low limits that are set automatically or manually. Alarms are reported through an

audible alarm in the freezer enclosure and through a contact closure that may be

connected to an external alarm. The Swift GUI provides options to temporarily sup-

press alarms and set a delay time before the alarm is reported via the contact closure.

A one-time temperature alarm suppression provided by the Swift software allows for

the initial cooling of the freezer after start-up.

AC power from 90 to 264 Volts is allowable, with a maximum current draw of about

3.0 Amps at 110 V and 1.5 Amps for 240 V.

2.4 – The Swift GUI Touch Screen

The Swift GUI is implemented on a touch screen control

panel on the front of the cabinet. Its capabilities are described

in detail later. General features of the control panel are:

• Set freezer control, alarm and communications parameters

• Provide password protected access to parameter changes

• Display freezer status

• Display temperature graph and event log

• Display diagnostic and service information

• Display freezer identiﬁcation information

Values for the following SU105U parameters are viewed and modiﬁed through

the touch screen.

Modiﬁable Values Accessible Values
