Sullivan-Palatek Compressor Repair Edmonton | Airtek

Repair starts with the complete system

A compressor fault can begin in the air end, controls, cooling circuit, separator system, motor, engine or the plant air network. We assess the complaint in context before defining the repair.

Sullivan-Palatek packages vary widely by generation and duty. Stationary equipment may use electro-mechanical controls, T1 or Q1 controllers, fixed-speed or VFD operation. Portable units add engine, aftertreatment and electronic control systems to the compressor package.

Evidence-led diagnosisFault history, operating readings and physical inspection guide the work.
System-specific inspectionControls, inlet regulation, cooling, lubrication, separation and discharge are assessed together.
Clear repair scopeFindings and recommended work are explained before repair decisions are made.

Equipment coverage

Sullivan-Palatek families we can assess

Coverage is based on the exact model, serial number, configuration, parts availability and condition. The families below identify the commercial and industrial equipment this page is built around.

Stationary · compact and mid-range

SPM, SP11 and SP13 rotary screw compressors

Shop and plant-air packages covering smaller modular machines through 60 HP-class systems, including tank-mounted, platform-mounted and enclosed configurations. Service may involve controller warnings, starting systems, inlet regulation, coolers, filters and separator circuits.

Representative families: SPM 5–10 HP · SP11 25–40 HP · SP13 40–60 HP

Stationary · production air

SP16+, SP20+, SP25, SP32 and VFD systems

Larger continuous-duty packages serving manufacturing and production environments. Diagnosis considers compressor loading, temperature, pressure control, motor and drive condition, separator differential, cooling performance and how variable demand affects VFD-equipped units.

Representative families: SP16+ 75–125 HP · SP20+ 125–200 HP · SP25 200–350 HP · SP32 300–450 HP · VFD

Stationary · established designs

Legacy D, D4, DG and LSC packages

Earlier open, enclosed and line-shaft industrial machines remain part of many working air systems. We identify the installed controls and package arrangement before assessing service items, regulation, high-temperature protection, drive components and air/oil separation.

Representative models: D-15 · D-20 · D4-25 · DG-30 · DG-40 · LSC Series

Portable · 110 to 375 CFM classes

Compact and mid-size portable diesel compressors

Tow-behind units used for pneumatic tools, construction, rental fleets and field work. Service can include compressor and engine fault tracing, load/unload control, sensors, inlet operation, cooling, oil carryover, couplings, blowdown and service-air delivery.

Representative models: D110PKUW · D185 variants · D210PHKR · D260PDKR · D300PD2KR · D375PHKR

Portable · high-output

D750, D900, D1150 and D1600 portable platforms

Larger portable systems add higher-capacity compressor circuits, electronically controlled diesel engines and model-dependent aftertreatment. Accurate intake information is especially important so compressor-side and engine-side faults can be separated efficiently.

Representative families: D750/D900 Series · D1150PXHD1CU4 · D1600PH1CU4

Configurations · verify first

Enclosed, tank-mounted, utility and special packages

Model suffixes can identify meaningful differences in engine, pressure, mounting and control configuration. Airtek confirms the data plate and installed package before advising on repair scope, maintenance requirements or replacement parts.

Best starting point: clear model and serial plate photos plus controller or fault-screen photos

Faster service intake

Send the machine details with the request

Sullivan-Palatek model names and suffixes matter. A complete intake helps us distinguish a stationary electrical or control issue from a compressor fault, and a portable compressor issue from an engine or aftertreatment event.

Common service complaints

Symptoms worth investigating

These are starting points for diagnosis, not proof of a failed component. Stop and safely isolate equipment when operating conditions, alarms or the manufacturer’s instructions require it.

High discharge temperature

Temperature warnings or shutdowns under load, especially as coolers foul or airflow changes.

Low pressure or reduced output

The unit runs but cannot meet normal pressure, recover promptly or support expected air demand.

Will not load or unload

Control solenoids, pressure signals, inlet actuation and regulation require systematic checks.

Oil in the service air

Excess carryover can involve oil level, scavenge return, separator condition or operating pressure.

Relief valve opens

Unexpected overpressure or incomplete unload behaviour needs prompt control-system assessment.

Controller alarm or shutdown

Capture the full code or message before resetting so sensor, protection and operating events can be separated.

Engine derate or speed loss

On portable units, engine faults and compressor loading conditions can both limit full-load operation.

Noise, vibration or leaks

Changes at the drive, coupling, air end, piping or fluid circuit should be assessed before they progress.

Repair process

A clear path from complaint to return to service

Identify

We confirm the model, serial, package configuration, application and reported operating symptom.

Diagnose

Technicians inspect the relevant compressor, control, cooling, motor or engine systems.

Define

Findings, parts considerations and the recommended repair scope are communicated for approval.

Verify

Completed work is checked against the original complaint and observable operating condition.

Service FAQ

Before you book

A few useful answers for plant teams, contractors and fleet managers.

Do you service both stationary and portable Sullivan-Palatek compressors?

Yes. This service page covers industrial electric rotary screw packages and portable diesel compressors. Final serviceability depends on the exact model, configuration, condition and parts requirements.

Can you assess older D, D4 or DG stationary compressors?

Yes, legacy equipment can be assessed. Send the full model and serial number because controls, starters, pressure ratings and package options can differ across generations.

Which portable models are included?

The scope includes Sullivan-Palatek portable diesel families from compact D110 and D185-class units through D210, D260, D300 and D375 models, as well as larger D750, D900, D1150 and D1600 platforms. Model suffixes should always be confirmed from the data plate.

What should I do before resetting a compressor alarm?

Photograph or record the complete alarm, shutdown message or fault code and note what the machine was doing when it appeared. Follow the equipment manual and site safety procedures; do not repeatedly reset a protective shutdown without determining why it occurred.

Can Airtek help with recurring high-temperature shutdowns?

Yes. High discharge temperature can involve oil level or condition, restricted coolers or filters, airflow, fan or belt condition, thermal regulation, sensors or operating environment. The cause should be verified on the specific package rather than assumed from the alarm alone.

Can you provide preventative maintenance?

Airtek can review service needs using the model, hours, environment and available maintenance history. Recommended intervals and materials must follow the applicable machine documentation and actual duty.

Do you service equipment outside Edmonton?

Contact Airtek with the equipment location and service requirement. We will confirm whether the request fits our current service area and the most practical way to assess the machine.
