Introduction:
The LUF-series LufranTM fluoropolymer inline water heater is designed to heat DI water with very stringent
cleanliness requirements. All wetted surfaces in this unit are fluoropolymer and PVDF material. There
are no metallic wetted surfaces. The cleanliness of these units has been confirmed by independent third
party testing. The cleanliness report is available upon request.
The Lufran fluoropolymer inline water heaters are available in wattages from 24kW to 312kW. These
units consist of one or more heating columns combined with a control system and all necessary power
distribution circuitry in a freestanding enclosure. The table on page 10 shows the various wattages with
the corresponding number of heating columns. The photo on the cover shows a typical Lufran unit with
two heating columns.
CE certification is available as an optional feature.

Engineering Information (Continued):
The maximum possible temperature rise through the heater is dependent upon the wattage of the unit
and the water flow rate through the unit. The following table illustrates the maximum temperature rise of
various models based upon the water flow rate through the unit.
The Lufran fluoropolymer inline water heaters include a comprehensive system of safety controls and
devices to insure safe and long-lasting operation. The list of safety devices includes but is not limited to
the following:
•EMO pushbutton
•Circuit breaker
•Ground fault (earth leakage) protection
•Pressure relief valve
•Liquid level sensor
•Leak detector (optional)
•High process temperature sensor

Engineering Information (Continued):
Facility Requirements:
Before installing the Lufran fluoropolymer inline water heater confirm the facility requirements listed
below.
Space Requirements:
The Lufran fluoropolymer inline water heater is constructed in a freestanding enclosure. This cabinet
includes the common framework for the heating column(s) as well as the electrical components. No
additional support is required.
The dimensions of the specific model are based upon the unit wattage. The cabinet assembly requires
ventilation. Locate equipment so that ventilation fans on the top and bottom of the enclosure and louvers
on the sides are not obstructed. The ventilation fan exhausts through these openings, preventing
overheating of the unit. Be sure to provide adequate clearance for normal operation and maintenance of
this heater.

Engineering Information (Continued):
Facility Requirements (Continued):
Water Plumbing Requirements:
This unit is typically supplied with a single inlet and outlet water connection located just inside the rear of
the cabinet. The connections are arranged vertically and do not offset from the horizontal center of the
unit. The inlet plumbing should also include a means to drain the unit for service. There are also
connections for the PRV valve and the leak pan drain. Reference the unit’s model number and the model
number key to identify the specific plumbing connections provided with your unit.
Electrical Requirements:
Reference the unit’s model number and model number key or the Electrical Specifications Table inside
the front door to identify the electrical power requirements of this unit. In addition, the model number tag
on the front of the unit includes the unit’s Wattage, Voltage, Amperage draw and Phase. Verify that the
incoming electrical service is rated and fused for the required amperage draw.
Ne pas dépasser la tension nominale. Des
dommages irréparables à l'appareil de chauffage
entraînera.
Do not exceed the rated voltage. Irreparable
damage to the heater will result.
NOTE: Ensure electrical power fusing and disconnects meet local jurisdictional
requirements. Fuse ratings noted in this document are for reference only.
Purge Gas Requirements:
A source of purge gas, nitrogen (N2) or clean dry air (CDA) is required for the heater element purge
system. All Lufran fluoropolymer inline water heaters use 6.4-mm (0.25-inch) compression fittings as the
purge gas inlet connection.
The purge gas supply must be regulated between 1.75 – 6.9 bar (25 – 100 psig) gas pressure. Each
heating column inside the unit will use approximately 141 l/hr (5 SCFH) of purge gas.
If the gas pressure is supplied lower than 1.75 bar (25 psi), the control’s safety circuitry will disable the
heater and indicate a safety alarm. If the gas pressure exceeds 6.9 bar (100 psi) equipment damage will
result.
Ne pas dépasser la pression de gaz pur de 6.9
bar (10
0 PSI). Des dommages irréparables à
l'élément de chauffage peut entraîner.
Do not exceed pure gas pressure of 6.9 bar (100
PSI). Irreparable damage to the heater may result.

Engineering Information (Continued):
Optional Communications:
-C1 Option: Ethernet:
The –C1 communications option adds
Ethernet communications to the PLC
controller. The network can interface with
the Lufran heater through the RJ45
connector included with the unit.
The Lufran heater is provided with the
following default IP Address: 128.1.105.100.
The Ethernet card has a default module ID
of 14. Once connected to the network, the
customer may wish to change the IP
address. Adjusting the IP Address or
performing other networking tasks with the
Lufran heater will require the use of NetEdit
software (3.5 or later), available from Host
Engineering. This software along with the
instruction manual is available as a free
download through their website:
http://hosteng.com
-C2 Option: DeviceNet:
The –C2 communications option adds DeviceNet communications to the PLC controller. The network can
interface with the Lufran heater through the DeviceNet mini male connector included with the unit.
The Lufran heater is provided with the following default node assignment: 63. Once connected to the
network, the customer may assign a new node to the Lufran heater.
If necessary, the EDS file can be downloaded from this address:
http://support.automationdirect.com/downloads.html
When one of the communications options are included with the heater, the main menu screen will be
modified to include a button to select this communication as the method for control of the unit.

Operator Interface:
Operator Interface Buttons:
There are two push buttons are located on the front panel of the unit.
Power On Button: When depressed, this button enables the main power safety contactor (1CON) and
readies the system for operation. It illuminates to indicate the system is in an operational mode.
Power Off Button: When depressed this button disables heater operation by disengaging the main
power safety contactor (1CON). It illuminates to indicate the main power is off.
Operator Interface Panel (OIP):
The operator interface panel is an intelligent flat panel display. It is designed to interchange and display
graphical data from a PLC by merely viewing or touching the screen. To ensure the effectiveness of the
panel, it is important to take the following precautions:
Do not press sharp objects against the screen.
Do not strike the panel with hard objects.
Do not press the screen with excessive force.
Many fields in the various displays can be adjusted by pressing the field value. This will
bring-up a keypad which will allow the operator to change the value.
