Description
Introduction
The Nordson Spectrum HD Feed Center conditions and supplies powder for
up to 16 automatic powder spray guns or can be a combination of automatic
and manual guns. It contains a High Density sieving and powder feed
system using the Nordson HDLV technology along with Ultra Sonic sieve,
level sensors, virgin feed and electrical / pneumatic controls via a Touch
Screen operator interface.
The Spectrum HD provides quick color changes and automatic purge
cleaning. The HD Hopper is the heart of the Spectrum HD Feedcentre;
receiving reclaim and virgin powder, sieving and feeding powder to all guns
using Nordson HDLV pumps.
Figure 2-1 Spectrum HD Powder Feed Center

Description
2-2
Part 7159651_01 E2012 Nordson Corporation
The feed center controls are designed to accommodate two HDLV transfer
pumps: a reclaim pump to transport over-sprayed powder from the booth
recovery system to the feed center, and a optional bulk feed pump that adds
virgin powder to the system as needed.
Both transfer pumps deliver the powder to the vibratory sieve, where it is
conditioned before delivery to the powder spray guns.
The color change operation is automatic. During a color change,the HD
Hopper cycles through a number of cleaning processes. High-pressure
purge air is pulsed through the powder feed pumps, hoses, and guns to
clean them of powder. This also cleans the sieve section and hopper itself
leaving minimal cleaning from the operator. The reclaim and virgin powder
transfer pumps can be purged manually, as required.
The Spectrum HD feed center requires a remote air extraction system that
provides a constant airflow through the enclosure, preventing powder
escaping into the spray room. The typical extraction system consists of an
afterfilter assembly consisting of an exhaust fan, primary cartridge filters,
pulse valves and controls, and final filters. A rectangular duct connection is
provided at the bottom rear of the feed center enclosure.

Reclaim and Virgin Powder Feed Options
The bulk feed systems is optional. Most systems will use at least one
reclaim system. Dual reclaim systems are often specified for coating wire
goods.
Refer to your system drawings for additional information and installation
information.
Reclaim Powder Systems: The HDLV transfer pump is mounted on the
cyclone stand. When the reclaim pump is turned on, air flows from the feed
center control manifold through 8-mm tubing to the pump operating air
regulator.
During a color change cycle, when the operator selects Pump Purge, the
valve opens and allows air at line pressure to flow through the pump and the
16-mm suction and delivery powder tubing to clean them.
Virgin Powder Feed System: A typical bulk feed system includes a HDLV
transfer pump as well a process valve to control system operation. The
process valve is typically connected directly to the air drop inside the feed
center electrical/pneumatic cabinet.
During a color change cycle, when the operator selects Pump Purge, the
valve opens and allows air at line pressure to flow through the pump and the
16-mm suction and delivery powder tubing to clean them.
NOTE: For HDLV transfer pump see technical manual on Nordson
emanuals website.
