Ultra Fryer fryers have UltraClear or UltraClear Plus built-in filtration, which the spec sheets say cleans shortening to increase food quality and extend oil life; Plus models add internal plumbing and pumps. It runs across the electric E-series, gas P-series and Right Size IR-RS lines, and each model's manual gives the filtering procedure.

## Key takeaways

- UltraClear and UltraClear Plus are the built-in filtration systems on Ultra Fryer units; the spec sheets say both clean shortening to increase food quality and extend oil life.
- UltraClear Plus adds all internal plumbing and pumps, per the UltraGold spec sheets.
- Built-in filtration is offered across the electric E-series, the gas P-series and the Right Size IR-RS line, in two to six vat configurations depending on the model.
- Every spec sheet lists six fast-flow filter envelopes as a standard feature, with pads, a stainless steel filter screen and triple filtration as accessories.
- The manufacturer's manual for the model gives the filtering procedure and schedule; repairs belong to Ultrafryer's authorized service network.

## What UltraClear and UltraClear Plus filtration are

Ultra Fryer units in our catalogue come with one of two built-in filtration systems, and the naming is consistent across the line: UltraClear on UC models and UltraClear Plus on UCP models. The UltraGold 14 electric spec sheet for B-E17-14-UC states that the UltraClear filtration system cleans shortening to increase food quality and extend oil life. The gas spec sheets for the P30-18 and P20-20 series use the same wording.

UltraClear Plus adds hardware. The spec sheets for B-E17-14-UCP, B-E20-18-UCP, B-E20-20-UCP and B-P30-18-UCP all describe UltraClear Plus as a system with all internal plumbing and pumps that cleans shortening to increase food quality and extend oil life. In the maker's video Ultrafryer Commercial Deep Fryer Tour & Filtering, Ultrafryer presents its Energy Star rated fryers and states that UltraClear filtration keeps oil clean and fresh longer.

Neither the spec sheets nor the video publish a filtering interval or an oil-life figure. The manufacturer's manual for the specific model gives the filtering procedure and any recommended schedule, and that manual is the document to follow.

## Which Ultra Fryer lines include the built-in filter

Built-in filtration runs across the Ultra Fryer lines in our catalogue: the electric E-series, the gas P-series and the Right Size IR-RS gas fryers. Their model codes end in UC for UltraClear or UCP for UltraClear Plus: the filter is part of the fryer rather than a separate portable unit.

- Electric E-series: E17-14 with 14 in. vats and a 35-45 lb (22 L) oil capacity per vat, E20-18 with 18 in. vats and 70-110 lb (36 L) per vat, and E20-20 with 20 in. vats and 125 lb (63.7 L) per vat. The spec sheets cover two to six vats.
- Gas P-series: P20-18 and P30-18 with 18 in. vats and 70-110 lb (36 L) per vat, and P20-20 with 20 in. vats and 125 lb (63.7 L) per vat. The sheets cover two to six vats on the P30-18 and three to six on the P20-18 and P20-20.
- Right Size IR-RS: a 20x14 gas fryer with 20 in. by 14 in. vats and a 65 lb oil capacity per vat, in two to four vat configurations per its spec sheet.

## What ships with the filter system

The spec sheets list what comes with the filter system. Every sheet lists six fast-flow filter envelopes as a standard feature, and the electric sheets also list a wash wand hose, a continuous drain board, a tub scraper and cleaning brush, and a drain cleaning rod and vat cleaning brush.

The accessories lists on the spec sheets include the following filtration-related items. The manufacturer's manual for the model explains how each is used with the filtration system.

- Fast-flow filter pads and a stainless steel filter screen
- Triple filtration
- A drain valve for the filter tub
- A boil-out hose
- A shortening disposal line, with a rear shortening disposal valve on the UCP sheets
- Heat tape and a shortening shuttle on some models

## Assembling the filter

The maker's video Ultrafryer Deep Fryer Filter Assembly Procedure shows the steps involved in assembling an Ultrafryer filter. Watch it before the first filtering session so the assembly order is clear, then confirm against the manufacturer's manual for the model, which is the controlling document.

Assembly is part of installation and first-time setup. A qualified, licensed installer must make the gas or electrical connections to local code before the fryer is commissioned. The electric spec sheets note that cord sets and plugs are not included, and the gas sheets specify 7 in. water column for natural gas and 14 in. water column for LP, with gas line sizes that vary by model and vat count.

## Filtering as part of daily oil care

A built-in filter changes the mechanics of oil care, not the routine. The general steps for draining, filtering, testing and changing fryer oil are covered in our guide to filtering and changing fryer oil and apply to any brand. What is specific to Ultra Fryer units is that the filter is built in, and on UltraClear Plus models the plumbing and pumps are internal too, so no separate portable filter machine is needed.

The spec sheets publish no filtering interval and no oil-life claim, so set the schedule from the manufacturer's manual for the model and your own oil testing. The UltraGuard automatic melt cycle, standard on the E17-14 sheets and optional on the E20-18, E20-20, P20-18, P30-18 and P20-20 sheets, gently brings shortening to temperature to prevent scorching and overheating. The E17-14 sheets also describe the UltraStat 23 controller, with ten keys for menu programming, as maintaining consistent temperatures and hold times.

## Gas and electric models as the spec sheets describe them

The electric E-series uses high-efficiency flat bar heating elements and is available in 208 V or 240 V, three phase. The E17-14 sheet lists 17 kW at 47 amps per vat on 208 V and 41 amps per vat on 240 V; the E20-18 and E20-20 sheets list 20 kW at 56 amps per vat on 208 V and 48 amps per vat on 240 V. Controller power on the electric sheets is 120 V, 60 Hz, single phase at 8.5 A, on a 6 ft cord at the rear right-hand side.

The gas P-series uses phased-array heat exchangers with pilotless electronic ignition. The P20-18 and P20-20 sheets describe the PAR-2 exchanger as suited to menu items that need consistent low temperatures over long periods, such as bone-in chicken; the P30-18 sheet describes the PAR-3 as built for higher heat and faster cooking times. The IR-RS sheet lists dual phased-array heat exchangers with infrared burners, total inputs from 240,000 BTUH on a two-vat unit to 480,000 BTUH on a four-vat unit, and controller power of 1.2 amps per vat plus 3.1 amps with the pump.

The P30-18 sheet publishes ASTM heavy-load results of a 2.30 minute French fry cook time, an average recovery time under 10 seconds, a production rate of 120 lb per hour and a cooking energy efficiency of 61.1 per cent. The P20-18 sheet lists an idle energy rate of 6,281 BTU per hour and a cooking energy efficiency of 60.1 per cent.

## Service, parts and questions

Filtration repairs, including pump or plumbing work on UltraClear Plus systems, belong to the manufacturer's authorized service network. The spec sheets list fast-flow filter envelopes as standard and filter pads as an accessory; ask Norpex about consumables for a model.

For questions about which Ultra Fryer model or filtration variant suits a particular menu, ask Norpex. General buying considerations are covered in our commercial fryer buying guide.
