PT-DZ21K Series

3-Chip DLP™ Projectors PT-DZ21K/PT-DS20K/PT-DW17K

High Reliability and Low TCO with Easy Maintenance

Low TCO and an Environmentally Friendly Design

The PT-DZ21K Series projectors lower the total cost of ownership (TCO) because they have a lamp replacement cycle of up to 2,000 hours*. Their environmentally friendly design also includes a low power consumption of 2,300 W.

* The values given for lamp replacement cycles are for landscape orientation. The usage environment affects the lamp replacement cycle.

Four-Lamp System Enables Stable, Extended Operation

The four-lamp system allows the projector to keep working even if a lamp should fail.
The Lamp Relay mode also operates the lamps alternately to enable 24/7 projection.
Quad, Triple, Dual and Single Lamp modes can be used.

Easy Lamp Replacement

For easier maintenance, you can replace the lamp from the rear. This makes it easy to replace a lamp while the projector is still in the mounting bracket or dual stacked.

Liquid Cooling System Attains a High Level of Reliability

This new liquid cooling system directly cools the DLP™ chip to improve performance and enable operation up to 45 °C (113 °F).*
It allows quiet (49 dB) and versatile use while stabilizing performance.
It also helps to make the body compact. And the system is hermetically sealed, so you don’t need to replenish the liquid.

* The operating temperature range is 0 °C to 40 °C (32 °F to 104 °F) when the fan control is set to HIGH ALTITUDE MODE (for altitudes from 1,400 m to 2,700 m (4,593 ft to 8,858 ft) above sea level). When the projector is used with the ET-SFR510 Smoke Cut Filter, the operating temperature range is 0 °C to 35 °C (32 °F to 95 °F), and the projector cannot be used in places at high altitude.

Eco Filter that Needs No Maintenance for up to 12,000 Hours*

The Eco Filter has an electrostatic Micro Cut Filter that collects minute dust particles with an ion effect. It combines with the dust-resistant cabinet to enable long-term use even under harsh conditions. Its maintenance cycle of up to 12,000 hours reduces hassle, and the environmental design lets you wash the filter with water and reuse it.**

* The usage environment affects the filter maintenance cycle.
** When washing with water, please follow the procedures listed in the operating instructions. Also, we recommend replacing the filter with a new one after it has been washed and reused twice. If the filter is not sufficiently clean after washing, replace it with a new one.
